Flowmaster Original 40 Series Offset/Offset Oval Muffler; 2.50-Inch Inlet/2.50-Inch Outlet (Universal; Some Adaptation May Be Required)

High-Flow Offset Design. The Flowmaster Original 40 Series Offset/Offset Oval Muffler features a fully offset design with 2.5-inch diameter outlets to allow gas to freely circulate without risk of backpressure. As a result, this muffler promises small performance gains for your F-150 to improve your throttle response and acceleration. 

Deep Tone. This muffler features a chambered internal core with packing material that removes unwanted resonance. This muffler produces a deep tone that only belongs to a Flowmaster muffler. 

One6-Gauge Steel. Flowmaster employed a 16-gauge steel shell to protect this muffler from outside abrasion, whether from rocks, salt, branches, or any other debris you climb over. 

Aluminized Finish. This muffler features a mild matte black exterior with an embossed Flowmaster logo for a stylish design. In addition, this finish is entirely aluminized to protect against rust and tarnishing that lead to rot. 

Fully MIG Welded. This muffler is 100% MIG welded for superior strength, sharp contours, and a leak-free design that guarantees long-lasting use. 

Limited Lifetime Warranty. Flowmaster backs this product with a lifetime replacement warranty against manufacturing defects. 

Application. The Flowmaster Original 40 Series Offset/Offset Oval Muffler is compatible with all 2021-2026 Ford F-150 models.
