EXCEPT Tremor and Black Appearance Package. This 3" diameter into dual 2.25" BORLA® Cat-Back™ system was specifically designed to enhance the power and sound of the Ford F-150 equipped with the 5.0L V8 engine. The system features the popular S-Type with no drone. 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. Systems with bright chrome on T-304 stainless steel tips are also available. Additional systems are available with different options for sound level, tip finish and tip exits.
