Description

The Flowmaster 40 Series Delta Flow Chambered Muffler uses a two-chamber design with Delta Flow® technology to increase exhaust scavenging for improved performance and reduced interior sound. Compared to standard 40 Series mufflers, this design produces a milder exterior tone and lower interior resonance while retaining aggressive performance characteristics.

Constructed of 16-gauge 409 stainless steel and fully MIG welded, the 40 Series Delta Flow Muffler is built for maximum durability. Its offset 2.50-inch inlet and outlet make it ideal for a variety of street, strip, and off-road applications, providing aggressive sound while remaining compact enough for versatile installations.

With no internal packing to blow out and a durable construction, this muffler delivers reliable performance for high-demand vehicles.
