Anytime you add substantial modifications to your C6 ZR1 Corvette such as heads & cam or run more boost, you'll need to address the exhaust system. The factory exhaust manifolds, as good as they are, keep you from realizing your engine's full power & performance potential. By smoothing and maximizing exhaust flow with a larger diameter full length header, you'll notice huge gains in power. American Racing Headers' full length C6 Corvette headers enable you to fine tune your vehicle to match your upgrades. This header system includes 18 gauge 1-7/8 inch primary tubing with .375 thick surface ground flanges, and 16 gauge 3 inch merge collectors with leak proof ball and socket flanges. American Racing Headers' exclusive cat forward x-pipe location maximizes power and allows you to run stock or aftermarket cat-back exhaust systems. This header system includes an off-road only x-pipe & severe duty 49 state legal cats, premium ARP Grade 8 header bolts, Flat Out Racing gaskets, Accuseal Band Clamps, 02 sensor extensions, and instructions engineered specifically for your C6 ZR1 Corvette. Not compatible with single or twin turbo systems.
