Exhaust manifolds gather the hot exhaust coming out of the engine's cylinders and route it away from the engine, throught the exhaust system and into the atmosphere. Some exhaust manifolds have the car's catalytic converter built in.
One of the most common causes of failure in exhaust manifolds are for cracks to form in the piping. This can come as a result of extended use over a long period of time or poor manufacturing. The usual sign of a bad exhaust manifold will be the sound of escaping gas, heard as a loud hiss.
Replacing an exhaust manifold could turn into a labor intensive job requiring the removal of many components on your vehicle. This depends on the type of vehicle invovled, however we recommend leaving this repair to experienced mechanics or certified shops.
We stock and sell a wide variety of quality exhaust manifolds from these manufacturers:
