Description
Overview
The Flowmaster Super 40 Series Chambered Muffler brings race-bred exhaust technology to the street and strip. Developed from Flowmaster’s Top Ten race muffler lineup, the Super 40 is built around Flowmaster’s proven Delta Flow® technology, delivering an aggressive, deep, and powerful tone with the performance benefits serious enthusiasts demand. If you want the unmistakable rumble of the Original 40 Series but with cleaner interior acoustics and improved flow, the Super 40 was engineered to give you the best of both worlds.
Its larger case profile makes it especially well suited to forced induction and high-horsepower vehicles, where the extra volume helps manage flow while keeping the signature Flowmaster sound loud and proud. On the street, that translates to a bold, muscular note; on the strip, it means a chambered muffler that can keep up with a hard-working engine.
Delta Flow® Performance and Sound
Delta Flow® technology is the heart of the Super 40. It’s what gives this muffler that deep, powerful character while reducing low interior resonance and unwanted drone. The result is an aggressive sound level that stays purposeful rather than muddy, pairing well with performance-oriented street/strip builds that want to be heard.
Built to Last
Durability is engineered in from the start. The Super 40 is constructed from 16-gauge aluminized steel and fully MIG welded for maximum strength and long service life under demanding conditions. A high-temperature paint finish helps the muffler stand up to the heat of everyday driving and spirited runs alike.
