Description
Overview
The Flowmaster Super 40 Series Chambered Muffler is engineered for street and strip drivers who want an unmistakably deep, aggressive exhaust note without sacrificing performance. Built around Flowmaster’s proven Delta Flow® technology, the Super 40 combines a larger case profile with smart internal chamber design to deliver the best of both worlds: bold sound and strong flow.
Its larger case gives the Super 40 that deep, powerful tone associated with the Original 40 Series, while the Delta Flow® technology adds meaningful performance benefits and keeps low interior resonance in check. The result is a muffler that sounds serious on the outside while staying more comfortable and controlled inside the cabin.
Built to Last
Durability is designed in from the start. The Super 40 is constructed of 16 gauge aluminized steel and fully MIG welded for maximum strength, then finished in high-temperature paint to help it hold up to the heat and demands of an active exhaust system. This is a chambered muffler made to take the abuse of daily driving and spirited runs alike.
Sound and Performance
If you’re chasing an aggressive sound level with real character, the Super 40 delivers a deep, powerful voice backed by the flow-focused engineering of Delta Flow® chambers. It’s a purpose-built exhaust upgrade for enthusiasts who want their vehicle to be heard and to perform.
