Description
The Flowmaster 40 Series Delta Flow® Chambered Muffler combines race-proven Delta Flow technology with durable 409 stainless steel construction. Designed for 4/6-cylinder engines, this two-chamber muffler features a 3.00-inch center inlet and dual 2.50-inch outlets for an aggressive exterior sound while reducing interior resonance. The Delta deflectors improve exhaust scavenging for enhanced performance and a milder exterior tone compared to the standard 40 Series mufflers.
Constructed of 16-gauge 409S stainless steel and fully MIG welded, the Flowmaster 40 Series Delta Flow Muffler is ideal for street, strip, and off-road applications. Its design eliminates internal packing that can blow out, ensuring long-lasting durability.
