C6 Corvette Z06 American Racing Headers 1-7/8 inch (2006-2013)

C6 Corvette Z06 American Racing Headers 1-7/8" Long Tube Header System (2006–2013)

For 2006–2013 C6 Corvette Z06 owners, the American Racing Headers (ARH) 1-7/8" Long Tube Header System upgrades the full flow path from the factory manifolds through a matching 3" x 3" X-pipe, then connects at the rear axle connection point to mate with your axle-back. It’s built to help the LS7 7.0L breathe more efficiently, sharpen throttle response, and deliver a harder-edged tone under load.
