Product Description


Bolt these Long-Tube Headers on your 2008-2009 G8 GT or GXP for a quick pick up of up to 28 horsepower and 29 foot pounds of torque. Your L76 engine will really respond. SLP's engineers developed these headers to maximize power through the entire rpm range with 1 3/4 inch primaries flowing into 3 inch collectors then into high-flow catalytic converters (included) that bolt to the factory Cat-Back exhaust. Headers come with ceramic coating inside and out to cut down on heat transfer, increase exhaust gas velocity, and reduce under-hood temperatures. All necessary hardware, gaskets and clamps are included for an easy installation.
