My friend has a full cat back exhaust with a Greddy Muffler that's shaped like the stock muffler on my 91 CRX SI. The exhaust came off a 90 hatch and I was wondering if this exhaust will fit my CRX without modification. I would like to buy it if it does.

 

It won't "bolt on" but all you need to do is shorten the pipe after the cat and before it makes that 90 degree turn over to the right hand side of the car. I think you have to take out something like 8 or 10 inches of pipe. The rest should bolt right up.
