Description

The Flowmaster 40 Series Delta Flow Chambered Muffler with a 2.50-inch offset inlet delivers aggressive exhaust sound while improving performance and reducing interior resonance compared to standard 40 Series mufflers. This two-chamber design incorporates Flowmaster’s race-proven Delta Flow technology, using Delta deflectors to enhance exhaust scavenging while controlling cabin noise.

Constructed from 16-gauge aluminized steel and fully MIG welded, this muffler provides long-lasting durability for street, strip, and off-road applications. The Delta Flow design produces a milder exterior tone and reduced interior resonance compared to standard 40 Series designs, while maintaining the deep, powerful Flowmaster sound that enthusiasts expect.

With a universal-fit design, 2.50-inch offset inlet, and dual 2.25-inch outlets, this muffler is ideal for custom exhaust setups where aggressive sound and reliable performance are required.
