Description
Overview
The Flowmaster Super 40 Series Exhaust Muffler brings proven race-bred technology to the street and strip. Developed from Flowmaster’s Top Ten race muffler lineup, this Super 40 muffler features Flowmaster’s Delta Flow® technology and a larger case profile that delivers the best of both worlds: strong performance flow and an unmistakably aggressive tone. Whether you’re building a naturally aspirated street car or a high-horsepower, forced-induction combination, this Flowmaster muffler is engineered to keep up.
Anyone who has set out to shop for exhaust knows the balance between sound and flow can be tricky. The Super 40 solves that with the deep, powerful sound of the Original 40 Series while adding the benefits of improved performance and reduced low interior resonance courtesy of the Delta Flow® design. The result is a car exhaust note that’s loud and purposeful without droning inside the cabin.
Built to Last
Construction is where this magnaflow-caliber muffler earns its keep. It’s made from 16 gauge aluminized steel and fully MIG welded for maximum durability, then finished in high-temperature paint to handle the heat and demands of a street/strip vehicle. This is a muffler designed to survive real driving and hard use.
