I am replacing the cat free stock H pipe on my car with an OR BBK Xpipe.
I bought a gasket at an auto parts store and it is still leaking so I went to the Ford dealer and bought a OEM one, except the shape of it is different than the one that I bought at the parts store.
First, there is two uneven sides, whereas the gasket for the Ford one is rounder on one side and flatter on the other.
Which side goes face into the manifold? The flatter or rounder?
