2dr/4dr exhaust compatability

i have a 92 Civic LX and like many others with 5th gen civics that i know, i need to replace my exhaust system from the cat-back. i figured i might as well get a performance exhaust and do it myself instead of paying through the a__ for midas to do it. i found a complete cat-back exhaust system for 159.00 at summitracing.com. it is a Monza pacesetter. it says that it is for 92-95 coupes 1.5 or 1.6 liter. i heard that this would work from a couple sources but i called a honda dealer today that said it wouldn't. if anyone knows about similarities in the 2dr and 4dr exhaust systems please let me know.

thanks for your help
