ok first off will an after market exhaust from a 1997 civic coupe fit a 1991 crx? the reason for this ? is i can get a 5zigen exhaust off a civic at my job i just have to get the stock exhaust to replace it from a junk yard. any info would help. they look to be routed the same under the cars except for the exiting tip will come out the right side of the crx.
