Description
Overview
The Flowmaster Super 40 Series Chambered Muffler brings race-bred exhaust technology to the street and strip. Developed from Flowmaster’s Top Ten race muffler lineup, the Super 40 was engineered for enthusiasts who want serious performance backed by an unmistakably aggressive sound. Built around Flowmaster’s proven Delta Flow® technology, this muffler delivers the best of both worlds: strong flow characteristics and a deep, powerful tone that late model muscle cars are known for.
What sets the Super 40 apart is its larger case profile. That extra volume makes it especially well suited to forced induction and high horsepower vehicles, where it manages sound and flow together to help your combination breathe. If you loved the deep rumble of the Original 40 Series, the Super 40 carries that same signature note forward while adding the performance benefits and low interior resonance that Delta Flow® technology is designed to provide.
Built to Last
Durability is engineered into every seam. The Super 40 is constructed of 16 gauge 409S stainless steel and fully MIG welded, giving it the strength to stand up to the heat, vibration, and demands of aggressive driving. A high-temperature paint finish adds to its resilience, helping the muffler look and perform its best over the long haul.
