ATP Automotive, also known as Graywerks, is a trusted supplier of exhaust manifolds and engine components. Over time, original exhaust manifolds can crack or warp from heat cycling, allowing hot exhaust gases to escape into the engine compartment — a condition that is both a performance and safety concern. The ATP 101721 replaces the failed OEM unit and restores the integrity of the exhaust system.
