The Borla Touring Cat-Back exhaust system (part number 140870BC) is built to add power and sound to the 2021-2025 Ford F-150 with the 2.7L and 3.5L EcoBoost V6 engines. This 3 inch into dual 2.25 inch system replaces the single factory tail pipe with a dual side (passenger-side) exit and a single 4 inch round black chrome tip on T-304 stainless steel at each tail pipe. It is built from premium T-304 austenitic stainless steel, superior to T-409, with ultra-smooth mandrel bends for maximum flow and CNC manufacturing for an accurate, bolt-on fit, and uses Borla's patented straight-through, multi-core technology to free hidden horsepower. The Touring sound level provides a mild, refined note with no interior drone. Add adapter 60556 for Crew Cab with Standard Bed (157.2 inch wheelbase) and adapter 60564 for Extended Cab with Long Bed (164.1 inch wheelbase). Because this cat-back mounts behind the factory catalytic converters, it is 50-state emissions legal. Borla exhaust is handmade in the USA and is backed by the Borla Million-Mile Warranty.
