How much modification would it take to make a 2dr Civic exhaust fit on a 94 GSR, if any?

 

flip it around and try it.... my wife's car (93 civic ex cpe) has a 94 gsr muffler on it and it fits perfectly. i wouldn't think the civic's muffler would've changed much (95 to 96), but don't know for sure, since when i had a 96 cpe, i threw out the stock muffler, and now that i have a 96 hatch, it doesn't really apply to your q... hope i helped.

 

Thanks. Need more info on the compatibility of the entire cat back.

 

i would also like to know.
