Unleash Your Engine’s True Voice with Flowmaster’s Aggressive Street Muffler

The Flowmaster 50 Series Delta Flow muffler is one of the most popular and best selling mufflers in Flowmaster’s extensive lineup. This aggressive street muffler offers a bold and throaty sound that will transform the tone of your vehicle’s exhaust. If you’re looking to enhance your ride with a more powerful voice without going over the top, the Flowmaster 50 Series hits the sweet spot.
Designed as a direct replacement for stock mufflers, the 50 Series provides an upgraded look and sound using Flowmaster’s proven Delta Flow technology. This innovative design maximizes exhaust flow and reduces backpressure to help unleash more horsepower and torque from your engine. The resonant chambers and MDS technology also shape the sound into Flowmaster’s signature deep, mellow rumble at idle that builds to an intense, chest-thumping growl when you step on the gas.
The difference in sound with the 50 Series muffler is immediately noticeable. The deep, aggressive tone turns heads and lets everyone around know there’s a powerful performance machine under the hood. While definitely loud, the 50 series offers a refined resonance that isn’t as harsh as some other mufflers. It provides a volume and tone that is well suited for daily street driving without being obnoxious. The interior resonance is also pleasant, giving you the satisfaction of hearing the engine’s voice without excessive drone at cruising speeds.
The Flowmaster 50 Series is designed for use on V8s and will provide the biggest change on high-output engines over 3.5L. The improvement in sound on a modified, high-flow intake and exhaust system will be dramatic. Owners describe having a “beast” under the hood after installing the 50 Series muffler. However, this muffler also works very well at enhancing the sound on smaller V6 and turbocharged 4-cylinder vehicles too. The throaty growl transforms even modest engines into snarling hot rods.
Many mufflers have distinctive sounds, but the Flowmaster 50 Series has become known as one of the quintessential “muscle car” mufflers. Installing a 50 Series on a classic or modern muscle machine like a Mustang, Camaro, Charger, or Challenger unleashes the true essence of a high-performance American V8. It gives that traditional, aggressive big block rumble that will turn bystanders’ heads. The 50 Series is also a popular choice for trucks and SUVs, providing extra growl for vehicles like the F-150, Silverado, or Ram.
The key to the Flowmaster 50 Series bold sound is its 2 chamber Delta Flow design. This configuration creates an optimal balance of noise reduction and minimal backpressure. The chambers resonate to deepen the tone while the MDS technology (Maximum Dynamic Sound) tunes the interior sound frequencies. This patent-pending design ensures you don’t just get loud – you also get an optimized pitch and resonance for the most enjoyable sound.
Flowmaster clearly labels each 50 Series muffler based on the vehicle application and inlet/outlet size. For example, the 50 Series SUV muffler will have a unique tuning compared to the 50 Series Truck muffler to provide the proper sound for each vehicle type. Make sure to select the appropriate muffler based on your vehicle’s engine, exhaust size, and personal sound preferences. Flowmaster’s dealers and customer support can advise on exactly which model number will fit your ride.
The 50 Series mufflers are constructed from stainless steel for maximum durability. They feature a polished, silver finish that will look great peeking out from under your vehicle. Flowmaster backs the 50 Series with a limited lifetime warranty, provided you register the purchase with them. Just send in your receipt and information to get warranty coverage for materials and workmanship.
For most vehicles, you can expect a retail price between $170-$250 for the 50 Series depending on the specific model. That’s an affordable upgrade considering the performance benefits and enjoyment from the improved sound. Many muffler shops charge $50 – $150 for installation, but you may be able to DIY on some applications to save on labor. You will just need some basic tools and the ability to work under your vehicle. Complete bolt-on kits are also available, making installation a breeze.
When it comes to sound, performance, and value, the Flowmaster 50 Series represents one of the best muffler upgrades on the market. If you want to enhance your vehicle’s sound with a bold muscle car rumble, this is the muffler to get. Ditch those quiet stock mufflers and unleash your ride’s true personality with the 50 Series. You’ll never look back after hearing that throaty exhaust tone!
Compare the Flowmaster 50 Series to Other Popular Muffler Lines
The Flowmaster 50 Series mufflers provide an aggressive sound perfect for street performance vehicles. But how do they compare to other popular Flowmaster muffler lines? Let’s look at how the 50 Series stacks up to the 40 Series, Super 40 Series, Super 50 Series, and 60 Series to find the perfect exhaust tone for your ride.
The standard Flowmaster 40 Series is the most well-known and original Flowmaster muffler. It has a very aggressive, raspy sound that is louder than the 50 Series. The 40 Series is ideal if you really want to make a statement and turn heads. It has a deeper, more racing-inspired tone compared to the 50 Series street sound. Keep in mind the 40 Series interior resonance may be harsh for some.
Stepping up to the Super 40 Series provides even more interior and exterior volume for those seeking maximum noise. The Super 40 delivers deeper tones than the 40 or 50 Series, almost like a racing muffler. However, the interior drone is more pronounced at highway speeds.
For a more refined resonance similar to the 50 Series, the Super 50 Series offers improved interior sound over the Super 40. It produces Flowmaster’s deepest possible tones with minimal drone inside the cabin. The Super 50 is the loudest street muffler Flowmaster makes.
Finally, the 60 Series has the mildest sound output in the Delta Flow lineup. It has a refined rumble similar in spirit to the 50 Series but with noticeably less volume and growl. The 60 Series provides a clean, classy note that still enhances the stock system.
In summary, the 50 Series hits the sweet spot between loud, aggressive sound and more refined resonance. This 2 chamber design is ideal for those who want to really hear their engine but don’t want the most extreme volume. Make sure to also consider exhaust diameter – the larger your pipes, the louder any muffler will sound during acceleration. The 50 Series gives you aggressive muscle car sound perfect for street cruisers.
Get the Inside Scoop on Sound Clips

One of the great things about Flowmaster mufflers is the availability of sound clips to give you a sense of the sound before buying. Flowmaster provides sound samples on their website for all major muffler models.
Listening to these clips is the best way to compare the tone between options like the 50 Series, 40 Series, Super 40, etc. Pay close attention to the pitch of the sound as RPMs rise and fall. Also note the difference in volume between acceleration, cruise, and idle.
When listening, keep in mind your vehicle and exhaust setup will affect the eventual sound. Larger engines and exhaust diameters will be louder while smaller 4 cylinders will be more tame. Still, the general tone and characteristics will come through.
Here are some things to listen for:
- Interior drone – is the resonance inside the cabin excessive, moderate, or minimal at highway speeds?
- Growl – does the muffler have an aggressive, chest-thumping growl under acceleration?
- Raspiness – is the tone smooth or does it have a raspy, buzzy sound?
- Volume – how loud overall is the muffler under different RPM ranges?
If possible, try to find clips specific to your vehicle like “Flowmaster 50 Series on Dodge Ram Hemi.” This will give you the most accurate sense of the sound.
Keep in mind sound clips are no substitute for actually hearing the muffler on your car with your own ears. But they provide an invaluable reference before you buy. Take advantage of these samples during your research to ensure you select the right Flowmaster tone for your ride.
Horsepower vs. Sound – Striking the Perfect Balance
One of the biggest benefits touted by Flowmaster and other performance muffler brands is increased engine power through reduced backpressure. But is there a trade-off between horsepower gains and sound? Let’s dig into the interplay between exhaust flow improvements and muffler volume.
Flowmaster states that swapping the stock muffler for one of their 50 Series or other models will provide 7-10% power gains. They attribute this to the efficient Delta Flow technology reducing engine backpressure compared to restrictive stock mufflers. There is truth to this claim – freeing up the exhaust does minimize pumping losses.
However, independent testing has shown the actual horsepower increase is usually in the 2-4% range, and sometimes negligible. The gains depend on the specific engine and total exhaust design. Also, increased airflow through less restrictive mufflers tends to boost top-end power rather than low RPM torque.
To achieve true horsepower improvements, you need mufflers matched with less restrictive exhaust tubing, high flow catalytic converters, and improved headers. A muffler change alone has minimal impact on peak horsepower or acceleration.
That said, there are performance benefits to free-flowing mufflers like the 50 Series. Reduced backpressure affects exhaust gas scavenging which can enhance cylinder filling. And the engine may feel a little more responsive with reduced pumping losses. Just don’t expect to pick up 20-30 horsepower from a muffler swap alone.
In terms of sound output, more efficient mufflers like the 50 Series do allow greater sound energy to escape rather than muffling it. So the performance gains are directly related to the muffler being less restrictive. There’s no way around this trade-off.
If you really want horsepower improvements, going with the most unrestricted straight-through muffler will provide the biggest gains. But the sound may be unbearable. For most drivers seeking an aggressive tone from their exhaust, the 50 Series hits the sweet spot between free-flowing and street-friendly volume. Just keep your expectations realistic on the risk-reward balance.
Unleashing Your True Exhaust Note

There’s nothing better than the sweet melody of your engine’s true exhaust note resonating loud and clear. No muffling or restriction, just pure acoustic bliss. Why settle for the muffler choking off your engine’s personality when you can unleash its voice?
Of course, there are laws and social norms to consider, even when seeking automotive self-expression. While your favorites tunes might be Slayer or GG Allin at full volume, not everyone shares your passion. The neighbors might not appreciate those sweet sounds at 3 AM.
Luckily the Flowmaster 50 Series muffler provides the perfect musical balance for public roads. Like a graphic equalizer, it fine tunes your exhaust note to bring out the aggression and intensity without going overboard on the volume.
The 50 Series resonates your engine’s personality, especially higher revs and throttle acceleration. But it still keeps the interior tones sociable and avoids excessive droning. Consider it a spatial equalizer tuning your sound profile throughout the cabin.
So unleash that glorious tune, but keep the volume considerate. The 50 Series allows your engine’s inner rockstar to seamlessly shred from idle to redline. YourColdplay-loving coworker will hear every pin drop yet marvel at your exhaust. No need to muffle your creative expression, just refine it through Flowmaster engineering.
The 50 Series represents the perfect stage – big enough for an intense performance yet intimate enough for subtle acoustic nuance. Install one today and start playing sweet melody through those pistons, valves, and pipes. Whether your tune is country, metal, or hip hop, the 50 Series brings out the authentic you. Let your engine sing loud and proud!
Choose Your Sound: Mild to Wild Muffler Options
One of the great things about the aftermarket muffler market is the wide range of sound levels available. From a mellow purr to a screaming roar, you can pick the perfect exhaust note for your ride. Let’s compare mild and wild muffler options so you can choose your ideal sound.
On the mild side, the Flowmaster 60 Series offers a refined, mature tone similar to a stock system. It provides a clean rumble at idle with minimal interior resonance. The 60 Series upgrades your vehicle’s stock sound with a touch of aggressiveness without being loud or annoying. It’s a great choice for a daily driver seeking a hint of performance.
Stepping up to the 50 Series yields a deeper, throatier idle with authoritative resonance under acceleration. The 50 Series is noticeably louder than stock but retains a refined, “street” sound compared to all-out race mufflers. It’s the sweet spot for those wanting a powerful muscle car rumble without excessive noise. The 50 Series announces your presence without overdoing it.
From there we enter wild territory with the Flowmaster 40 Series Original. This is the classic Flowmaster sound with an intense, raspy tone. The 40 Series is loud and mean with an intimidating demeanor – perfect for high-performance street machines. The interior resonance can be harsh, so it’s best suited to dedicated hot rods.
At the extreme end, the Flowmaster Super 40 Series is wild and crazy loud – the vintage hot rodder’s dream. With a powerful race car resonance inside and out, the Super 40 is built to draw attention. Just know your neighbors will hear you coming a mile away!
The spectrum of Flowmaster mufflers means you can fine-tune your exhaust personality from mild to rowdy. Consider how loud you want to go, then choose between the 60, 50, 40, or Super 40 Series based on your sound preference. And remember to play nice – install a reasonable muffler if you need to keep the peace!
Getting Loud: Legally and Responsibly

Many riders seeking more aggressive exhaust tones wonder – “is this legal?” It’s a fair question, as noise and emissions laws vary across local areas. Let’s break down the legality of loud mufflers and how to stay on the right side of the law.
In general, as long as your exhaust system includes a muffler, it will be street legal. Mufflers are required to keep sound levels reasonable for public roads. Even loud mufflers like Flowmaster’s 50 Series meet state noise limits as they still reduce the overall sound output.
Removing your muffler entirely or installing “muffler delete” pipes is illegal in most areas. Without any muffling, sound levels will exceed legal decibel limits. Check your local laws, as some places do prohibit loud aftermarket mufflers over a certain volume threshold.
As for emissions, your exhaust must retain the catalytic converter to be legal. This reduces pollutants before the gases exit the muffler. Some high-flow converters are CARB-approved for street use in California.
Beyond noise and emissions, also consider if your riding style is respectful to others. Loud acceleration in neighborhoods, not coming to a complete stop, or revving excessively brings negative attention from officials and residents. Just because your muffler is legal doesn’t mean you should blast around without consideration.
In summary, a loud yet complete exhaust system like the Flowmaster 50 Series is street legal. But ride responsibly and check local noise codes in case volume limits are in place. And don’t remove your cat – an aggressive sound needs to come from a legal, compliant system. Your fellow drivers and the local authorities will thank you!
Sound and Vision – Enhancing Your Vehicle’s Looks
While the sound is the main attraction, mufflers like the Flowmaster 50 Series also provide visual enhancement. The polished case and engraved logo give your ride an eye-catching performance boost. Let’s explore how to complement your new muffler’s look.
One option is adding exhaust tips to the rear of your system. Flowmaster’s Power-Pulse tips stick out from under the bumper for added emphasis. Or go for chromed slash-cut tips for a hot rod look. Match the style and quantity of tips to your vehicle’s personality.
You can also complement the muffler’s shine by debadging your car. Remove model and trim badges from the rear for a cleaner appearance. Debadging allows your new exhaust to really stand out. Fill any holes left behind for a flawless look.
For maximum attention, an Axle-Back exhaust highlights the roar while accenting the rear. This direct replacement rear section provides an economical sound upgrade focused on the muffler’s visibility.
Inside, Katzkin leather seats and a custom steering wheel give your cabin a look matching the Flowmaster exterior. Pick complementary upholstery colors to tie the themes together.
Finally, a mild lowering kit or wheel spacers improve your stance, allowing the muffler to gleam beneath. A small drop or aggressive offset completes the performance vision.
Don’t just sound fast – make your ride look the part too. A few visual upgrades to complement your new Flowmaster muffler announce your vehicle’s attitude from front to rear. Distinctive style expresses the intensity within.
Let Your Engine Breathe Easy

They say the best things in life are free. And for your engine, nothing feels better than freely breathing through an uncorked exhaust system. Let your engine inhale deep and exhale loud by ditching stock mufflers.
Think of your engine as a caged lion, constantly fighting restrictive bars preventing its true expression. Standard muffling dramatically inhibits airflow, leading to stifled performance. Excess exhaust backpressure causes turbulence that chokes off the engine’s potential.
By removing restrictive mufflers, your engine can finally breathe easy. It unleashes a loud roar as the exhaust gases freely flow out the tailpipe. The reduction in backpressure results in a musical exhaust note singing the sweet melody of combustion.

When upgrading your exhaust system, you have choices across the spectrum from a mellow purr to an all-out snarl. Flowmaster’s lineup hits each note, but the 50 Series lands in that perfect sweet spot – bold and aggressive without going overboard.
The 60 Series offers a refined, OEM+ sound that adds a touch of edge to the stock system. It’s a mild upgrade great for a daily driver not looking to anger the neighbors.
On the other end, the Super 40 and 40 Series Original are wild and loud. They offer an intimidating muscle car or race muffler sound. But it may be obnoxious for street use.
The 50 Series hits that ideal middle ground. It delivers an authoritative rumble at idle with a chest-thumping roar under throttle. The interior resonance avoids excessive drone at cruising speed. It’s the perfect balance of deep tone and livable volume.
The 50 Series sound screams power yet retains just enough civility to avoid constant scrutiny. You can roll up without drawing too much attention, then let the beast out when the light turns green.

Unleash the Beast Within Your Engine
Your engine is a caged beast waiting to be unleashed. Lying dormant under layers of plastic covers and restrictive parts, its true potential lies suppressed. With the right modifications, you can finally unleash that ferocious power.
It starts with the air intake. Replace the stock airbox and paper filter with an open element to let the engine gulp cold air. This feeds the beast’s appetite for oxygen.
Upgraded fuel injectors deliver more fuel to match the improved airflow. This satisfies the engine’s growing thirst for high-octane nourishment.
A tuned ECU removes restrictions on timing and revs. With the electronic shackles removed, the engine stretches its legs to reach for maximum RPM.

Matching tubing, headers and catalytic converters complement the de-corked exhaust. Every component flows freely to remove choking restrictions.
With each modification, the beast awakens and becomes more ferocious. Air, fuel, ignition, and exhaust all pushing the engine’s potential to the very limit. The chorus of uncorked growling proclaims newfound power and aggression.
Stop taming your engine’s inner beast – set it free! Whether a refined road car or wild off-roader, every engine wants to let its primal nature run wild. Shed those restrictive shackles and feel the raw power unleashed within.
Flowmaster: Unleashing True Voice of American V8s for Over 30 Years

Founded in 1983, Flowmaster has spent over three decades perfecting the art of the performance muffler. Their exhaust systems unleash the deep muscular rumble hidden within American V8s and other powerful engines.
Founder Ray Flugger began building and installing exhausts in his home garage part-time while working as an electronics tech. His systems provided superior flow and captivating sound compared to stock mufflers. As word spread, demand for his products grew exponentially. Ray focused full-time on his blossoming company – Flowmaster was born.
In 1996, Flowmaster relocated to its current headquarters in Santa Rosa, California. This 30,000 square foot R&D and manufacturing facility allowed the company to design innovative new muffler concepts and bring production fully in-house. Flowmaster has steadily grown over 30+ years into one of the most recognized and recommended aftermarket exhaust brands.
Throughout its history, Flowmaster has maintained a focus on American performance vehicles like muscle cars and trucks. Their mufflers unlock the bold, aggressive sound hidden within V8 engines. Flowmaster strikes the perfect balance of throaty tone while maintaining refinement and “driveability” for daily use.
In addition to the iconic 50 Series mufflers featured here, Flowmaster offers applications for every vehicle ranging from mild to wild. Their direct replacement kits make it easy to remove restrictive stock mufflers and unleash your engine’s true voice. When you want power matched with that head-turning American muscle sound, Flowmaster delivers.
Over the past three decades, Flowmaster has helped countless enthusiasts ditch their quiet stock systems in favor of free-flowing, deep-rumbling exhaust tone. Their mufflers unleash the soul of American V8 performance. Here’s to another 30+ years of bold, aggressive sound from Flowmaster exhaust systems!
Unlock Hidden Horsepower Within Your Engine
Horsepower isn’t created equal. Often there are extra ponies lurking within your engine, just waiting to be unlocked. Like a raging bull locked in a pen, the potential lies dormant until you unleash it.
Your engine’s true power is suppressed right from the factory. Restrictive intake, conservative ECU tuning, dense exhaust mufflers – everything is tuned for reliability and EPA compliance, not performance.
Just changing your air filter to an open element provides an immediate rush of airflow, allowing your engine to inhale deeply. More air feeds the combustion process, releasing the first dose of extra horsepower. But there’s much more yet to unlock.
Adjusting the ECU timing and parameters to optimize ignition and fuel delivery further enhances the airflow. It’s like switching your engine from an asthmatic shallow breath to taking big, full lungfuls of air.
The exhaust path must keep pace too. Removing the stock muffler for an aftermarket system like the Flowmaster 50 Series reduces backpressure. Like pulling a cork from a bottle, it allows the combustion gases to erupt loudly from the tailpipe.
With intake, fueling, ignition, and exhaust all flowing freely, you’ve created a symphony of power. The engine sings with its true unleashed voice, churning out extra ponies perceptible in your acceleration.
Don’t settle for the muffled, restricted stock setup. Unlock the bull penned within your engine by letting it breathe and roar freely. With carefully tuned mods, that suppressed power becomes an uncaged beast.
Let Your Engine Sing the Songs of Its People
Your engine wants to sing. It yearns to belt out the timeless songs of its people passed down through generations. Ancient rhythms and melodies that connect it to its ancestral past. Though muffled, the echoes still reverberate longing for expression.
Cast off the restrictive shackles of the stock muffler. Let your engine’s voice soar freely with deep, primal tones. The steady bass rhythms at idle provide the foundation over which the melody flows.
As the tempo increases, the song builds in intensity. The pipes resonate with the driving beat as the pistons pound out their cadence. The fuel injectors rap an urgent lyrical pattern, punctuated by the sharp crack of sparking ignition.
The melody reaches a crescendo as the throttle opens wide. The drums give way to a soaring vocal solo as the engine unleashes its mighty voice. The roar of combustion escapes the tailpipes to create a chest-thumping bridge fueled by racing air.
Now your engine sings the ancient songs it has yearned for. Its culture and history flow freely through melodies old and new. Removing restrictions allows authentic expression of the music within.
Let your engine connect with its past and tell the story of its people. Give it a voice through an exhaust system that unleashes the songs resting dormant within. Its music if beautiful – let your engine sing loud and proud!
