C6 Corvette American Racing Headers 1-3/4" Long Tube Header System (2005–2013)
For 2005–2013 C6 Corvette Base and Grand Sport owners, the American Racing Headers (ARH) 1-3/4" Long Tube Header System replaces the factory manifolds and upgrades the full flow path to the rear axle connection point, where it then mates to your axle-back (factory or aftermarket). It’s built to improve exhaust efficiency, sharpen throttle response, and deliver a deeper, more aggressive tone under load—with your choice of catted or catless configurations.
