ATP Graywerks Exhaust Manifolds are designed to fit and function like the original part, restoring the exhaust system and eliminating dangerous leaks. With quality guaranteed through the 101558 certification process, ATP Exhaust Manifolds are the optimal choice for reliable and long-lasting performance. ATP exhaust manifolds transport burnt exhaust gasses from the engine to the exhaust system. Over time, these manifolds can crack or warp, releasing hot exhaust gas into the engine compartment and potentially into the passenger cabin, creating a hazardous situation. Replacing a broken manifold with an ATP part is the best way to ensure safety and restore the exhaust system to working order. ATP Exhaust Manifolds are crafted from high-grade materials for long-term durability and corrosion resistance. ATP manifolds are custom-engineered to OE-like specifications and are rigorously tested to meet stringent quality standards. With ATP Exhaust Manifolds, you can trust that your vehicle will be safe and running optimally.
