Exhaust question
 

Ok, so i know for a fact that the "inlet" of the cat is different for '90-93 and 94+... but, i see everywhere that brand new cat-back systems listed for 90-97 are all the same part number.
will a '96 cat-back exhaust fit my '91? i'm talking about the flanges. i know the header-to-cat flange is angled different. and a '94 cat won't fit a '93....what about the after-cat pipe? it's the corksport exhaust. if that makes any difference.
thanks!
