Improved Scavenging. Upgrading to the Flowmaster 40 Series Delta Flow Offset/Offset Oval Muffler could grant you an aggressive new sound and better throttle response out of your F-150. Flowmaster designed this muffler without internal packing and an offset design to improve air circulation and eliminate blowout. In addition, Flowmaster utilizes proprietary Delta Flow technology that improves scavenging to reduce backpressure altogether and increase the performance of your engine. Use this muffler for road or race use. 

Eliminates Dissonance. Eliminating packing materials and implementing proprietary Delta Flow technology also has the intended consequence of eliminating dissonance that drones out the noise produced in your muffler. As a result, your muffler will belt out a deep growl without that unwanted resonance that bugs your neighbors. 

Durable Construction. Flowmaster utilized state-of-the-art 16-gauge aluminized steel for a strong, durable, and corrosion-resistant finished product. Trust this muffler to stand up to everyday abuse, whether from salt, debris, or water that kicks up underneath your F-150 and damages its surface. 

Sleek Appearance. Enjoy a sleek race-style appearance, thanks to an embossed Flowmaster logo, aluminized black powder, and mild exterior tone that transform the look of your F-150. 

Application. The Flowmaster 40 Series Delta Flow Offset/Offset Oval Muffler is compatible with all 2021-2025 Ford F-150 models, though some adaptation may be required.
