Description
The Flowmaster 40 Series Delta Force Race Muffler is engineered for high-performance racing applications where a muffler is required while still maintaining aggressive exhaust sound and excellent power characteristics. Utilizing Flowmaster’s race-proven Delta Flow technology, this two-chamber race muffler delivers strong exhaust scavenging with effective sound control compared to open headers.
Designed to reduce decibel levels significantly over open headers, this muffler is ideal for track, competition, and regulated racing environments. The internal chambered design contains no packing material, ensuring consistent performance and sound output without the risk of blowout during extreme use.
Constructed from durable 16-gauge 409 stainless steel and fully MIG welded, the Flowmaster 40 Series Delta Force Race Muffler is built to withstand harsh racing conditions. Its oval body and straight-through center inlet and outlet configuration support high exhaust flow while maintaining durability and reliability under sustained high heat.
