The 3"diameter into dual 2.25" Borla Cat-Back was specifically designed to enhance the power and sound of the Ford F-150 with the 5.0L. The system features Borla'S Polyphonic Harmonizer Technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound. The systems is tuned for the aggressive ATAK sound with no drone inside the vehicle. The dual side (passenger side) exit configuration replaces the single factory tail pipe, and has single 4" round black chrome on T-304 stainless steel tips on each tail pipe. Using Borla Stainless Steel Polish p# 21499 is NOT recommended with these black chrome tips.

We suggest cleaning the tips with hot water and a microfiber cloth. Borla Cat-Back & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive Borla Sound of Power respected by enthusiasts everywhere.
