C6 Corvette American Racing Headers 2" Long Tube Header System (2005–2013) For 2005–2013 C6 Corvette owners who want maximum airflow and a harder-hitting exhaust personality, the American Racing Headers (ARH) 2" Long Tube Header System upgrades the flow path from the factory manifolds through a 3" X-pipe mid-section, then mates to your axle-back at the rear connection point. It’s a premium, engineering-first solution for LS2 and LS3 C6 builds where throttle response, mid-range pull, and high-RPM breathing matter. This system is offered in catted or catless configurations, uses merge collectors with scavenger spikes, and is built from 304 stainless steel with 3/8" laser-cut flanges for a strong seal under heat cycles.
