I searched it doesn't really answer my question.

Will a stock 2000 civic si exhaust fit on a 98 civic coupe?

 

It should, those chassis are pretty much the same. Although, I think the piping on the SI's stock exhaust is the same diameter as any stock 96-00 civic. I could be wrong though, anyone else? Another way to find out an answer is to look at some exhaust shops online or locally and find part numbers for both exhausts, and then compare.

 

thanks thats what i figured but I wanted to be sure. I'll call up honda tommorow, hopefully they'll tell me a definate answer.
