I have an 84' 244, and I was wondering if anybody made performance parts for my brick. I had to replace the exhaust manifold recently and it cost nearly $80 total to fix, but after finishing and not breaking any bolts, I bump into a friend of mine and we get to talking about this, and he says "why didn't you just put a set of headers on it? It wouldn't have costed much more to do." I didn't even think of it. Anyways, now the nuts on the downpipe rattle loose and I don't know the part number for the metal gasket between the manifold and the downpipe. Any help would be great. Thanks.
