Description
Overview
The Flowmaster Super 40 Series Chambered Muffler delivers the deep, powerful exhaust note that made the Original 40 Series famous, now enhanced with Flowmaster’s Delta Flow® technology. Engineered with a larger case profile, the Super 40 gives you the best of both worlds: serious performance flow and an unmistakably aggressive sound. It’s a proven choice for classic muscle car builds where attitude and reliable street performance matter.
At the heart of the Super 40 is Delta Flow® technology, which balances that iconic deep tone with reduced interior resonance. The result is a muffler that sounds mean outside the vehicle while keeping unwanted drone in the cabin under control, so you can enjoy long drives without fatigue and still turn heads at every stoplight.
Built to Last
Durability is built in from the ground up. Each Super 40 is constructed from 16-gauge aluminized steel and fully MIG welded for maximum strength and long service life. The high-temperature paint finish helps the muffler stand up to the heat and demands of an active exhaust system, making it a dependable addition to your build.
Sound & Performance
If you’re chasing an aggressive, muscular exhaust character, the Super 40 chambered design is tuned to produce a deep, powerful sound that complements the flow benefits of the Delta Flow® chamber technology. It’s the go-to option for enthusiasts who want their classic muscle car to be heard as well as felt.
