The rumble and roar of a finely-tuned performance exhaust system can be music to any car enthusiast’s ears. And when it comes to bolt-on mufflers, Flowmaster remains one of the most trusted names on the market. In this post, I’ll provide an in-depth look at Flowmaster exhaust kits – from the different types available to how to pick the ideal system for your ride. Whether you drive a classic muscle car, import tuner or full-size pickup, Flowmaster makes a kit to give you that deep, throaty sound that will turn heads as you fly by.
An Overview of Flowmaster Exhaust Kits
Flowmaster offers several lines of direct replacement and universal fit kits to upgrade your stock exhaust. They range from their Original Budget System for a subtle rumble to the racy Super 40 line favored by street rods. Here’s a quick overview of what they have to offer:
- Original Budget Systems: Flowmaster’s entry-level line provides a mellow tone for daily drivers. Available in single and dual configurations using the Delta Flow muffler.
- American Thunder: A notch louder than Budget, with a moderate interior resonance. Uses the FlowFX muffler, ideal for trucks and muscle cars seeking a crisp exhaust note.
- 40 Series: The most popular Flowmaster line, the 40 Series Delta Flow muffler outputs an aggressive exterior sound with minimal drone inside. Available in single, dual and cat-back kits.
- Super 40: Taking the 40 Series design further, Super 40s deliver deeper tone outside but remain comfortable inside thanks to chambered internals. Made for high-performance applications.
- Force II: The hottest-selling Flowmaster kit, the Force II features an unrestrictive straight-through interior to maximize airflow. Aggressive sound levels make it ideal for street rods.
- Flowmaster also offers specially-tuned systems for late model muscle cars like the Mustang GT500, Camaro SS and Challenger SRT Hellcat.
As you can see, Flowmaster exhausts run the gamut from mild to wild, but all are engineered to provide power gains with an authoritative voice.
Picking the Right Flowmaster Kit for Your Ride
With so many options, choosing the perfect Flowmaster kit for your application can be tricky. Here are some tips on selecting the right exhaust system:
Match the Sound Level to Your Goals – Are you seeking a refined rumble or an all-out snarl? Flowmaster kits range from a deep purr to a wide-open snarl, so decide how aggressive you want the exhaust note to be. Muscle cars and hot rods can handle the loudest setups, while trucks and sedans may want something more moderate.
Look at Pipe Diameter – Larger diameter piping reduces backpressure, but also increases volume. Flowmaster’s Super 40 and Force II lines utilize 2.5″-3″ pipes that allow high-RPM power gains. For a mellow sound on a stock engine, 2.25″ piping should suffice.
Complete Kits Save Hassle – Many Flowmaster kits include all necessary pipes, mufflers, tips and hardware for installation. This eliminates the need to piece together a custom system. Measure carefully or enlist a shop’s help to ensure a complete kit properly fits your car.
Verify Fit – Carefully check that the kit is made for your vehicle’s make, model, year and engine. Custom work may be needed to adapt universal kits. Flowmaster’s tech line can advise you on fitment questions.
Cat-Back vs. Axle-Back – Cat-back systems replace everything from the catalytic converter back, while axle-back kits only swap the rear pipes and mufflers. If you want the greatest sound and power gains, a full cat-back is preferred.
Consider a Professional Install – Most Flowmaster kits can be tackled at home with hand tools, though having a shop’s experience pays off. They can fabricate pieces as needed for a professional fit and finish. Get quotes first, as labor costs can mount quickly.
While the final choice comes down to your specific ride and personal taste, following these guidelines will lead you to the right Flowmaster exhaust for your needs.
Evaluating Sound Levels Across the Flowmaster Lineup
One of the biggest considerations when selecting a Flowmaster exhaust is the sound it will create. From a refined growl to a wide-open wail, Flowmaster offers levels to suit any enthusiast. Here’s how the major product lines compare:
Budget Systems – As the name implies, BudgetSystems produce a mild exhaust note outside the car and minimal resonance inside. There is a slightly deeper tone over stock, but overall volume is close to OEM levels. This makes Budget a smart choice if you want an upgrade without drawing too much attention.
American Thunder – Turning things up a notch, American Thunder generates a moderate rumble outside that owners describe as “crisp” and “clean.” The interior resonance is more noticeable but not intrusive, adding a performance feel during acceleration. Overall volume is still quite reasonable for daily street driving.
40 Series – Here’s where Flowmaster’s exhaust sound starts to get more aggressive. The 40 Series mufflers produce a raspy idle and a louder tone under acceleration. There is some interior drone, though strategic chambering keeps it from being excessive. The 40 Series sound is ideal for muscle cars and performance-oriented trucks.
Super 40 – Representing a hot-rodder’s dream, the Super 40 design unleashes a deep, commanding exhaust bark that rivals any system on the market. The rumble at idle actually belies how much louder the Super 40 gets at wide-open throttle. The interior resonance can be strong, so these kits are best for dedicated enthusiast vehicles.
Force II – When you want to make the most savage exhaust roar legally possible, Force II is Flowmaster’s answer. The straight-through muffler design produces a riotous sound under hard acceleration that Flowmaster describes as a “volcanic eruption.” Force IIs are built for race-ready street machines, as the interior drone can be extreme.
So as you move up through Flowmaster’s ranges, the sound output goes from modest to monstrous. Compare YouTube clips to pick the perfect pitch for your ride!
Installing a Flowmaster Exhaust Kit – DIY or Dealer Job?
Once you’ve picked out the perfect Flowmaster exhaust kit for your vehicle, it’s time to get it installed. Here we’ll look at whether it’s best to tackle the job yourself or let the professionals handle it.

Carefully weigh the DIY vs. professional options to choose what suits your skills and budget. And be sure to have a shop inspect any self-installed system. Proper exhaust placement is critical for safe operation. Either route, you’ll soon be out cruising in style with your new Flowmaster exhaust!
Expected Horsepower Gains with a Flowmaster System
One question on every enthusiast’s mind is: “How much power will this new exhaust add?” While results vary based on your specific engine setup, installing a Flowmaster kit – especially a cat-back system – typically generates solid horsepower and torque increases. Here’s an overview of what you can expect:
Trucks/SUVs – For pickups or SUVs with higher-displacement V8/V10 motors, look for rear wheel horsepower gains of 10-15HP, with torque increasing 15-25 lb-ft in the 3000-4000 RPM range. That improves acceleration noticeably, especially when hauling or towing.
Muscle Cars – Classic V8 pony cars see some of the biggest gains from an aftermarket exhaust like Flowmaster. Look for 15-25 additional HP thanks to reduced backpressure and improved scavenging as engine speed climbs. The extra torque down low beefs up that muscular acceleration even more.
Imports – Smaller import motors see modest but worthwhile increases of 8-12 HP, with torque typically rising 10-15 lb-ft between 2500-6500 RPMs. Those light cars really come alive with Flowmaster systems optimized for their smaller stock manifolds.
Diesels – Because diesels depend heavily on exhaust gas flow, they see excellent gains from a less restrictive system. Expect 15-22 HP more from a Flowmaster diesel kit, with torque jumping 20-35 lb-ft for stronger towing ability.
While a realistic 1-2 MPG decrease in fuel economy is typical, the across-the-board power boost more than compensates. And the sound alone makes driving fun again! Any time the exhaust can allow an engine to breathe easier, performance improves.
What Does a Flowmaster Exhaust Kit Cost?
Flowmaster exhausts are reasonably priced for the performance they provide. Let’s break down what to expect:
Direct-Fit Kits – These model-specific complete cat-back or axle-back systems range from $500 up to around $1000. The cost depends on materials used and tubing size. Figure $700-$800 for their most popular 40 Series.
Universal Kits – Designed to fit multiple vehicles, universal kits cost less – usually $400-$700 depending on mufflers chosen. But custom fabrication for your particular car adds $200 or more to the expense.
Components – Buying separate Flowmaster mufflers, tips, clamps, tubing etc. provides the most flexibility for custom builds but also runs $700-$1,200 or beyond, after paying for install labor.
Add-Ons – Optional items like stainless steel polish, exhaust jackets and additional sound dampening materials can add $100-300+ to the total.
Shipping – Count on $50-$150 for insured ground shipping of a complete exhaust kit to your home or mechanic’s shop.
While not cheap, when you consider the performance and enjoyment increases, Flowmaster exhausts deliver great bang for your buck. And a quality kit should last for years down the road.

The Expertise Behind Flowmaster’s Sound and Performance
The reason Flowmaster exhaust kits deliver that signature muscular sound is smart internal design. Here’s a look “under the hood” at what makes their mufflers and tubing so effective:
Delta Flow Technology – Flowmaster mufflers utilize a tapered internal chamber that allows more laminar flow and less turbulence than traditional designs. This smoothes the exhaust pulse to reduce interior resonance while still generating a strong exterior tone.
Aggressive Muffler Shaping – The oval or rectangular shape of Flowmaster muffler bodies increases internal volume compared to stock mufflers. More volume means lower sound frequencies for that aggressive rumble.
Strategic Sound Absorption – Interior baffles and chambers inside Flowmaster mufflers are tuned to absorb specific frequency bands. This cancels out harsh overtones but still allows the throaty exhaust sound to come through.
Wide-Open Interiors – Many Flowmaster mufflers use straight-through perforated cores to minimize internal turbulence. This reduces backpressure that can choke off a high-performance engine.
Mandrel-Bent Tubing – Exhaust pipes are carefully mandrel bent to maintain a consistent inside diameter throughout. This prevents exhaust flow from being obstructed at bends, further improving cylinder scavenging.
Stainless Steel Construction – Using stainless steel, especially for the internal components, resists corrosion from hot exhaust gases. This maintains free-flowing performance as the system ages.
It takes this kind of obsessive engineering to create the legendary Flowmaster sound. Whether you’re looking for a mellow rumble or balls-out roar, they have a kit to make your ride come alive!
Materials Used in Flowmaster Exhaust Products
To ensure both top-notch performance and maximum durability, Flowmaster constructs their exhaust components from the highest quality materials. Here’s an overview:
- Stainless Steel – From the muffler internals to exhaust tubing, stainless steel makes up the majority of Flowmaster products. Its high-temperature resistance prevents corrosion even after thousands of miles of use.
- Aluminated Steel – Their Budget Series mufflers feature aluminated steel shells over stainless internals. Aluminum coating helps prevent exterior rusting.
- Aluminum – Flowmaster uses lightweight aluminum for supplemental components like exhaust tips, clamps and support brackets. Anodizing protects against corrosion.
- Carbon Fiber – Select products like Flowmaster’s Force II cat-back make use of carbon fiber for reduced weight and increased strength. This exotic composite material is very heat-resistant.
- Fiberglass Packing – Interior chambers place fiberglass sound-absorbing insulation inside the mufflers to dampen unwanted frequencies and harmonics. The material lasts for years.
- Rubber Hangers – Soft rubber hangers isolate exhaust movement from the chassis to prevent rattles and cracking due to vibration. Durable composite hangers are offered too.
- Silencing Mats – Some kits include additional heat-shielded matting that affixes to the floorpan, reducing unwanted resonance inside the cabin.
No matter which Flowmaster line you choose, you can be confident the construction quality is top-notch. Follow the recommended care and these kits will provide a lifetime of trouble-free performance.

How Flowmaster Exhaust Kits Affect Gas Mileage
One question often asked about aftermarket performance exhausts is: “How much will this hurt my vehicle’s fuel economy?” While horsepower and sound increases are the main goals, it’s understandable to be concerned about gas mileage as well.
The effect on fuel efficiency from installing a Flowmaster exhaust kit depends on several factors:
- Vehicle Type – The engine size and power output plays a big role. The same Flowmaster kit will likely reduce mpg more on a 300 HP V8 than a 150 HP 4-cylinder.
- Driving Style – Aggressive driving negates some of the mpg benefit of stock exhausts. So installing a Flowmaster system has less impact if you regularly push the engine hard.
- Muffler Size – Larger diameter mufflers like Flowmaster Super 40s and Force IIs allow reduced backpressure. But their greater volume hurts economy more than a smaller performance muffler.
- Complete vs. Axle-Back – Replacing the entire exhaust system from manifold to tailpipe affects flow dynamics more than just an axle-back kit. Expect a bit less mpg penalty with just a rear muffler swap.
Under normal driving, the fuel economy difference may only be 1-2 MPG lower than stock. However, if you frequently run your high-powered engine hard, a difference of up to 4 MPG is possible. Installing new headers can also compound the effect.
In most cases, the added enjoyment and performance easily justify the slight drop in fuel efficiency – it’s just the cost of tuning an engine to breathe more freely. But you can always dial back your right foot when needing to conserve gas. For serious mileage, Flowmaster also offers low-restriction Budget Systems designed for economy.
Are Flowmaster Exhausts 50-State Legal?
With catalytic converters and emissions equipment mandatory on all new vehicles, it’s understandable to be concerned your state may prohibit installing a cat-back or axle-back Flowmaster exhaust kit. Fortunately, you need not worry – Flowmaster exhausts are 50-state legal.
The key reasons Flowmaster kits remain emissions legal:
- They only replace the rear muffler section, not the catalytic converter.
- The OEM catalytic converter remains intact and fully functional.
- Exhausts are designed not to negatively affect emissions.
- Flowmaster mufflers meet Federal EPA noise level requirements.
- Kits are CARB certified for sale in California.
- Emissions components like oxygen sensors and pre-cat pipes stay in place.
The only exception would be removing emissions equipment like the catalytic converter while installing a Flowmaster exhaust. This is prohibited by federal law. An exhaust shop won’t perform this work.
But just upgrading to a cat-back or axle-back Flowmaster kit has no effect on your vehicle’s emissions control systems. The improved engine performance and sound levels are fully compliant across all 50 states. Flowmaster stands behind their legal status.
So while it may sound deliciously illegal, you can rest assured a new Flowmaster exhaust gives you guilt-free speed and sound!
Most Popular Flowmaster Kits – Sound Clips and Reviews
With so many Flowmaster exhaust options, it can be hard choosing what’s right for your car. Here we’ll highlight some of their most popular kits and how owners describe the sound. Listen to clips yourself to pick your favorite!

Using Flowmaster Exhausts for Racing Applications
While Flowmaster kits are designed as street performance upgrades, their free-flowing muffler designs can also provide a competitive advantage in racing applications. Here are some tips on using Flowmaster exhausts at the track:
Pick a High-Flow Design – Opt for maximum airflow models like the Force II or Outlaw that minimize backpressure robbing power from a highly-tuned racing engine.
Use a Wide Tube Diameter – Bump up to at least 2.5″ or 3″ piping to reduce flow restrictions and keep things humming at high RPM.
Go With Stainless Steel – Stainless stands up to racing heat cycles better than aluminized steel. And it sounds phenomenal.
Get a Longer Pipe – Allow some extra length so the exhaust tone isn’t overly deafening in an enclosed metal race car interior.
Mount Tips Safely – Make sure long exhaust tips don’t extend dangerously close to tires or oil pan to avoid damage if you spin.
Tune Accordingly – Have your racing shop make appropriate fueling and timing tweaks to optimize performance for the less-restrictive Flowmaster exhaust.
Check Noise Limits – Make sure the exhaust sound remains legal depending on class rules. Muffler swaps may be disallowed in some categories.
While a peppier exhaust can help performance on street vehicles, the effects are even more impactful in a race car constantly run at high RPM. Consult your rule book and then unleash your racer’s hidden power with Flowmaster!
Maintaining Your Flowmaster Exhaust System
Flowmaster exhaust kits are built to last, but performing some simple periodic maintenance ensures they continue delivering great sound and performance for years. Here are a few tips:
Clean With Soap and Water – Use a mild soap and water solution to remove grime and road debris from the pipes and chrome exhaust tips. Avoid harsh chemicals.
Remove Carbon Buildup – Use a silicone-based cleaner to dissolve carbon deposits inside the tailpipes and muffler outlets to maintain free airflow.
Check Connections – Ensure clamps and mounts remain tight. Snug loose clamps by hand or with a screwdriver to prevent leaks over time.
Inspect for Damage – Look and listen for any new rattles indicating a cracked weld or loose component. Address issues promptly before greater damage occurs.
Lubricate Hangers – Spray rubber insulators and hangers with silicone lubricant so they don’t dry out and potentially crack from vibration.
Replace Gaskets – If any exhaust leaks develop at gasket surfaces, install fresh high-temp gaskets to restore a tight seal and prevent blowing out.
Consider Heat Tape – Adding heat tape to the pipes in cold climates reduces the chance of ice blockages in winter.
With this occasional care, your Flowmaster exhaust will sound factory-fresh for the life of your vehicle, enhancing performance and smiles each time you drive!
