    Description

    Get the original aggressive Flowmaster sound that puts serious punch into your vehicle's presence and power. The Flowmaster Original 40 Series Muffler maximizes horsepower, torque and flow with its two-chamber design-the original two-chamber Flowmaster muffler.

    If the roaring sound of an engine is music to your ears, you'll love the Flowmaster 40 Series. Aggressive sound is maximized outside, while high-volume interior resonance lets you hear every push of the pedal. It's this total sound design that makes the Flowmaster 40 Series the centerpiece of many of Flowmaster's outstanding American Thunder Exhaust Systems.

    Ideal for early muscle cars, off-road rides and dual exhaust cruisers, the Flowmaster Original 40 boasts the quality construction you'd expect from Flowmaster. Each Flowmaster muffler is built with 16-gauge aluminized steel for corrosion resistance and fully mig-welded for maximum durability. Best yet, your Flowmaster Original 40 Series Muffler boasts a 3-year warranty.

    Bought and installed these original 40 series mufflers on my 2001 monte carlo. It makes a great roaring sound that's controlled as per the throttle response. I can take off with easy acceleration and it makes a noticeable sound (roar) I slam the pedal to the metal and it gets much louder which is exactly the type of sound how and when I wanted. No interior drone. So this was done on my stock everything v6 3.8L engine. Now i can imagine the sound from these mufflers onna v8

    Excellent quality
