Description
Overview
The Flowmaster Super 40 Series Exhaust Muffler brings race-bred technology to the street and strip, delivering the deep, powerful tone enthusiasts expect from a genuine Flowmaster muffler. Developed from Flowmaster’s Top Ten race muffler lineup, the Super 40 features Delta Flow® technology and a larger case profile that balances serious performance with an aggressive sound. If you’ve been searching for a performance exhaust that sounds as good as it flows, this is a muffler built to deliver.
Constructed of 16-gauge 409S stainless steel and fully MIG welded, the Super 40 is engineered for maximum durability under real-world conditions. A high-temperature paint finish helps it stand up to the heat of a hard-working exhaust system, making it a dependable centerpiece for a street rod build or a broader car exhaust upgrade.
Key Benefits
The Super 40’s larger case profile provides the best of both worlds — performance and sound — especially on forced induction and high-horsepower vehicles. It carries the deep, powerful sound of the Original 40 Series but adds the performance advantages and low interior resonance that come from Flowmaster’s Delta Flow® technology. That means an aggressive exterior note without the harsh drone inside the cabin, so your exhaust automobile setup stays enjoyable at cruise and commanding at wide-open throttle.
