Right now I really hate driving with a leak on my exhaust and sound really crappy in city, but sound nice on the highway. It had a inch or two between the exhaust flange and the header flange. I could put on a 96-00 Civic coupe after market cat-back exhaust like Apexi onto my 96 civic hatchback?? what's the different about civic hatchback and coupe exhaust?? the length of the exhaust? Need some help before I take my exhaust I have right now to the shop to custom fit onto my GSR motor I just swapped not to long ago. So it would bolt on to my test pipe and header.
