Designed as a direct replacement for the factory cat-back exhaust, the new COBB Cat-Back exhaust system for the Mitsubishi EVO X has been completely redesigned to improve the look, sound and performance of this system. Tubing diameter was increased to 3" and bends were kept to a minimum with large radii for optimum flow characteristics. Fitment was extensively worked to ensure maximum ground clearance to accommodate cars with very low ride heights. It uses all of the stock mounting points and is compatible with the factory cat pipe as well as the previously released COBB High Flow Cat Pipe.
