96 Civic coupe axle back mufflers should bolt on...but it might be a tight stretch. i used to have a 5zigen civic 96 coupe muffler bolted to my stock integra piping long time ago, but took it off after only a couple weeks because it wasnt tight enough and i started to get an exhaust leak.

btw, if youre interested, i have the cat back piping from 5Zigen in near perfect condition for sale h: $50 + shipping :rick:
