i'm putting a 94+ gsr in a 93 civic dx...i just about completed the motor and i'm starting to think about the other stumbling blocks...i ordered a high flow cat (2.5"), a gsr header with a 2.5" collector and a civic dx catback exhaust all 2.5". I noticed that the bolt holes on the gsr header flange doesn't match those of the cat. Now i'm getting a little nervous of what else lies ahead....is there anyone who can give me a heads up? Thanks
