Performance exhaust systems let your engine breathe easier while giving it an aggressive, throaty growl. And one of the most popular systems for domestic V8s is the Flowmaster 60 Series Muffler. This iconic muffler strikes the perfect balance between noise reduction and free-flowing performance.
An Iconic Sound for Muscle Cars and Trucks
The 60 Series was one of Flowmaster’s first performance mufflers when they burst onto the scene in the early 1980s. And it remains one of their most popular models today. This muffler gives your ride a deep, rumbling idle and a roaring wail under hard acceleration. It’s the perfect sound for classic muscle cars, hot rods, trucks, and performance SUVs.
Many 60 Series owners say this muffler really makes their engine come alive. It’s often described as the quintessential hot rod sound. The interior resonance adds a visceral depth that enhances the driving experience. You not only hear the 60 Series, you feel it in your bones!
Dialed-In Tone Across the RPM Range
This muffler offers a wide spectrum of rich tones no matter where you are in the rev range:
- At idle, it has a lumpy, cammy lope that screams old school muscle.
- Cruising down the freeway, it has a refined bellow that isn’t droney or annoying.
- Stand on the gas and it breaks out into a deep, rumbling wail. The louder you go, the better it gets!
The sound is always proportional to your right foot. It grows along with the RPMs to accentuate the acceleration. The interior resonance adds an aggressive, raw edge to the exhaust note. This gives your engine a race-inspired vibe.
Optimized for Peak Performance
The Flowmaster 60 Series is an offset, reversed-flow muffler. This means the inlet and outlet are on opposite sides at different levels. The exhaust gases follow a winding path through the interior chamber.
This geometry slows down the exhaust for noise reduction. But it also creates an efficient scavenging effect for reduced backpressure. The large core and slash-cut tips further optimize flow.
Reduced backpressure improves power, throttle response, and fuel economy. Many owners report gains of 5-10 horsepower after installing a 60 Series muffler. And you’ll really feel the increased torque and acceleration!
Aggressive Looks to Match the Sound
The 60 Series has an imposing exterior to complement its commanding voice. The beefy case is made from aluminized steel or polished stainless steel.
It features either a black powdercoat or polished finish, depending on the model. And it’s all capped off with a pair of slash-cut chrome exhaust tips.
This muscular muffler looks right at home on a classic muscle car or hot rod. The modular design allows you to configure it exactly how you need for your chassis. You can have the tips pointing backwards, rotated to the sides, or adjusted to any angle in between.
Made for Both Street and Track
The versatility of the Flowmaster 60 Series makes it ideal for street-driven muscle cars and track-only race cars alike.
It’s engineered as a more refined street/strip muffler. It has a more balanced tone that isn’t as piercing as a dedicated racing muffler. Yet it still gives an aggressive exhaust note for high-performance driving.
The Flowmaster sound also ensures you get noticed out on the streets. There’s no question when you pull up next to someone at a stop light! But it’s not overly obnoxious for regular driving. It has just the right presence.
