Significant attention was devoted to the packaging of this exhaust. 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. Designed as a direct replacement for the factory cat back exhaust, 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. Turboback includes: COBB 3" SS Downpipe - Widened 3" mandrel-bent stainless steel downpipe; COBB 3" SS Testpipe - High-flow catalytic converter for optimal exhaust flow; COBB 3" SS Quad-Tip Catback Exhaust - Beautiful fabrication and awesome rumble.
