Hey guys i need an opinion if you have experience with exhaust systems please,
A buddy of mine has a 95 Acura Legend Coupe 6 speed, he recently changed the exhaust to a full straight thru... he is having a problem I hope you guys can help me figure out, the exhaust was custom built using SS upto the exhaust manifold, when first done, the shop used silicon gaskets which leaked and caused exhaust gases to come out thru the miniature space, and into the engine bay area from both manifolds (3 + 3), he went back to the shop and they apologized and installed metal gaskets. The problem was fixed for a few hours and somehow the thing loosened of something again and his exhaust is again leaking into the engine bay (much more noise and backfiring). So I am thinking it could be one of two things and i need your opionions becuase i am not sure, he cannot figure it out, and the shop is giving him a run around.....I think it can be either that the part of the exhaust that attaches to the manifold was not built right (it is a y-pipe), and perhaps there is too much stress on it exagerated by the heat/expansion. OR when they built the exhaust they DID NOT install a flex-pipe (I checked and they did NOT) and at the shop all seemed well but after 2-3 hours of driving with not flexpipe the movement of the exhaust stresses the junction between the manifolds and the custom y-pipe/downpipe and loosend the seal.
Thanks alot if you can advise me here, i need to help my brother out.
