Wow...first of all, this forum is for pre-1988 Civics and CRXs. If you have a 2002 Civic then post it in the correct forum please.
Second, why do you need to know what parts from other cars will fit yours? Just buy aftermarket parts made for your car, those are the ones that will fit the best.
If I had to guess however, I'd say the closest part matches for your car would be the 02-05 Si, and the 02-06 RSX, but I don't know for sure whether parts like an exhaust are really going to be totally interchangeable from any other car except another 01-06 Civic.
