It is constructed of T304 stainless steel, fully polished to a show quality finish. Featuring cast flanges for superior strength and leak-free seals and dual 2.5 inch piping with quality flex-joints. All necessary hardware is included for a quick, easy, and worry free installation. It replaces the factory pipe that goes between the OEM header-primary catalytic and secondary catalytic and bolts directly to the exhaust. Because a catalytic converter is removed, it is to be used on race and or off-road vehicles only. Throttle response is enhanced, adding a growl of authority under acceleration while providing a reasonable tone at cruising and idle speeds. The DC Sports exhaust adds a much needed voice to the aggressive looks and sporty handing that comes on the Genesis V6 Coupe. Tested, designed and developed in house by DC Sports.
