Things to keep in mind when buying

Many exhaust manifolds have a pre-converter or catalytic converter that bolts to the manifold. It is against the law for a salvage yard to sell a converter so if yours is bad don’t expect to get this part. You have to buy rebuilt or new. Its a good question to ask your mechanic and the company you are dealing with.

Installation Tips

When installing an exhaust manifold if it’s equipped with an O2 sensor verify that. If it has a gasket, replace it. If the EM is equipped with studs for the down pipe (Y-pipe) verify these are in good shape. If not, replace them.

Ongoing maintenance

If it has a pre-converter have your exhaust checked periodically according to your owners manual.
