C6 Corvette American Racing Headers 1-7/8 inch (2005-2013)

C6 Corvette 1-7/8" Long Tube Header System by American Racing Headers (2005–2013)

For 2005–2013 C6 Corvette Base and 2010–2013 C6 Grand Sport owners, the American Racing Headers (ARH) 1-7/8" Long Tube Header System replaces the factory manifolds and upgrades the full flow path with a matching 3" X-pipe, then connects at the rear axle exhaust connection point to mate with your axle-back (factory or aftermarket). It’s built to improve exhaust efficiency, sharpen throttle response, and deliver a more aggressive tone under load.
