Looking for increased performance, better mileage and better sound out of your late model car, truck or SUV? Livernois Motorsports Exhaust Products are here to help!! For the 2008-2009  Pontiac G8 with the powerful 6.0 or 6.2 liter engine and the 2014-2017 Chevy SS sedans, Livernois Motorsports Exhaust Products offers this true high flow, larger diameter, free flowing cat-back exhaust system. These cat-backs are made in America of T304 Stainless Steel featuring patented sound cancellation technology, and mandrel bends.
