Description
Overview
The Flowmaster Super 40 Series Chambered Muffler was developed from Flowmaster’s Top Ten race muffler lineup and refined for serious street/strip duty. Built around Flowmaster’s proven Delta Flow® technology, the Super 40 delivers the deep, powerful tone that made the Original 40 Series famous while adding meaningful performance and dramatically lower interior resonance. Its larger case profile gives you the best of both worlds — aggressive sound and strong flow — making it an ideal match for late model muscle cars, especially those running forced induction or high horsepower combinations.
Delta Flow® Performance & Sound
At the heart of the Super 40 is Delta Flow® technology, engineered to scavenge exhaust gases efficiently while producing a bold, distinctive exhaust note. The result is an aggressive sound level with reduced drone inside the cabin, so you get race-inspired attitude on the street/strip without the fatigue of unwanted resonance. Whether you’re building a naturally aspirated muscle car or a boosted, high-horsepower setup, the Super 40 is designed to keep up.
Built to Last
Durability is built in. Each muffler is constructed of 16 gauge aluminized steel and fully MIG welded for maximum strength and long service life. A high-temperature paint finish helps the case stand up to the heat and demands of a hardworking exhaust system. The chambered, race-derived design is engineered to perform mile after mile.
