The job of an exhaust header is to transport exhaust gas from the engine to the exhaust system. Over time the original exhaust header may rust leaking hot exhaust gas into the engine compartment. These gases can find their way into the passenger cabin creating a dangerous situation. The best way to repair a broken header is to replace it with a new one. The ATP 101330 stainless steel exhaust header is an improvement from the original steel header. Our header is constructed from stainless steel making it rust resistant. Manifold and flange gasket, bolts, and locking nuts are included making this part ready for installation right out of the box.
