Seems trying to find someone to shave some material off the face of an exhaust manifold requires a secret handshake and a decoder ring. Is it really that difficult? Anyone know a shop in San Antonio that can do it? I've already called Duffin, no go.
My exhaust shop has a belt sander for truing up manifolds. Not cheap. It goes through belts like crazy. I have no idea how feasible that might be depending upon how much material you want to remove.
