Description
The Flowmaster 40 Series Delta Flow Chambered Muffler delivers an aggressive exhaust tone with excellent street, strip, and off-road performance. Featuring Flowmaster’s proven Delta Flow® technology, the dual-chamber design enhances scavenging for improved performance while reducing interior sound. The design offers a milder exterior tone and reduced interior resonance compared to standard 40 Series mufflers, making it ideal for enthusiasts seeking aggressive sound without excessive cabin noise.
Constructed from durable 16-gauge aluminized steel and fully MIG welded, this muffler is built for long-lasting performance under demanding conditions. Its 2.25-inch center inlet and outlet allow for universal fitment on most 4- and 6-cylinder applications. No internal packing means the muffler maintains consistent sound quality without blowout concerns.
