Product details
Flowmaster introduces our Force II stainless steel cat-back exhaust system for the 2021-2026 Ford F-150 trucks with the 2.7, 3.5, and 5.0-Liter engines.

This 3 chamber muffler has a resonance chamber to reduce interior sound, ideal for towing or long haul situations. Mandrel bent 3.00-inch to dual out 2.50-inch 409 stainless steel tubing allows for maximum exhaust flow and durability. This system uses larger 4.00-inch polished stainless steel tips for a custom look. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation.
