Product Details

ATP Parts 101270 exhaust manifold transports burned exhaust gases from the engine into the exhaust system, helping restore the factory exhaust path on Ford Mustang models. Over time, manifolds can crack or warp and allow hot exhaust gases to escape into the engine compartment. Replacing the damaged manifold helps eliminate those leaks and return the exhaust system to proper operation. This part cross-references XR3Z9431DC for the same application.

Common Problems It Can Address

• Exhaust leak at the manifold
• Ticking or puffing noise from the engine bay
• Burning exhaust smell near the vehicle
• Heat escaping into the engine compartment
• Failed inspection related to exhaust leakage
