Welcome Message from 1A Auto

Our aftermarket manifolds are some of the highest quality replacements on the market!

If your vehicle's exhaust is getting loud and the exhaust noise is coming from under the hood or your car has failed your state's yearly emission tests then this is the part for you.

Replacing a broken manifold is easiest with a direct replacement manifold that will fit correctly and bolt up to you original engine and exhaust system. This manifold is a direct fitting replacement and includes the catalytic converter as the original did.
