The BORLA Cat-Back system 140879BC was specifically designed to enhance the power and sound of the Ford F-150 equipped with 3.3L engine. It includes 4" black chrome on T-304 stainless steel tips and a split rear exit configuration. Using BORLA Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. The entire system is made of T-304 stainless steel and utilizes computer numerical control (CNC) manufacturing techniques that ensure an accurate fit. This system features the ATAK sound level that gives you our most aggressive sound level with no drone. It is also available with bright chromed tips (part number 140879). There are also systems available for the 3.3L F-150 that offer different options for sound level, tip finish and tip exits.
