Description
The Flowmaster 40 Series Delta Flow Chambered Muffler combines aggressive exhaust sound with improved performance and reduced interior resonance. Featuring Flowmaster’s race-proven Delta Flow® technology, the two-chamber design enhances exhaust scavenging for better throttle response and performance while maintaining a milder exterior tone compared to the standard 40 Series.
Constructed from durable 16-gauge aluminized steel and fully MIG welded, this muffler is built to withstand demanding street, strip, and off-road applications. With no internal packing, the sound quality remains consistent over time without risk of blowout. Its oval body and universal configuration make it suitable for a wide range of custom exhaust setups.
