Description
Overview
The Flowmaster Super 40 Series Chambered Muffler is built for enthusiasts who want a deep, powerful exhaust note paired with real performance gains. Featuring Flowmaster’s proven Delta Flow® technology, the Super 40 delivers the best of both worlds: the aggressive, unmistakable tone that made the original 40 Series famous, now refined with improved flow characteristics and reduced interior resonance. Whether you’re building a weekend cruiser or a street-driven classic muscle car, this chambered muffler is engineered to make a statement.
Delta Flow® Technology & Sound
The Super 40’s larger case profile is the key to its dual-purpose design. The Delta Flow® internal chambering optimizes exhaust scavenging for stronger performance while keeping cabin drone and resonance in check. The result is that deep, powerful sound the 40 Series is known for, without the excessive interior boom that can wear you down on longer drives. If you want an aggressive tone that turns heads at every stoplight, the Super 40 delivers.
Built to Last
Durability is engineered into every seam. The Super 40 is constructed from rugged 16-gauge aluminized steel and is fully MIG welded for maximum strength and long service life. A high-temperature paint finish helps protect the case against the elements and the heat cycles of daily driving, so your muffler looks and performs its best mile after mile.
