This 3" diameter into dual 2.75" Borla Cat-Back system features the classic S-Type sound level with no drone inside the vehicle, and dual 3.5" X 3.28" "square" bright chrome on T-304 stainless steel tips on each tail pipe. Installation REQUIRES removal of the Factory Valance Tips.

Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
