Description
The Flowmaster Super 40 Series Chambered Muffler is engineered to deliver maximum performance with an unmistakable deep and aggressive exhaust tone. Featuring Flowmaster’s proven Delta Flow® technology, this muffler improves exhaust scavenging while helping reduce interior resonance compared to traditional chambered designs.
With a larger case profile than the Original 40 Series, the Super 40 offers the best balance of performance and sound. It retains the classic deep, powerful tone of the Original 40 Series while producing a deeper exhaust note and enhanced exhaust efficiency. This makes it an excellent choice for high-horsepower street-driven vehicles that demand aggressive sound and performance.
Constructed from 16-gauge 409 stainless steel and fully MIG welded, the Super 40 muffler is built for long-term durability under demanding conditions. The dual 2.50-inch inlet and dual 2.50-inch outlet configuration makes it ideal for custom dual-exhaust applications requiring maximum flow.
