My girlfriend just bought a 92' XJ and it has a crack in the exhaust manifold. She needs to have it SMOGed before she can regester it. we are looking for the cheapest replacement part we can find, either aftermarket or OEM. Any recomendations as far as brands or websites would be great. Thanks in advance. :banghead: Also any recomendations as far as RTV to use when installing it would be good too.
