Magnaflow Fox Body SS X-pipe
 

I bought this new and had it on my '91 for less than 50 miles. Didn't really like the sound and it hung kind of low but I am sure it was me installing it incorrectly. So I replaced it with a H-pipe.
Cost $339.00 new from summit and I would say it is still in "like-new" condition and will take $225 plus shipping. I no longer have Paypal so it will have to a money order or cashiers check.
