Why would you want a 20+ year old exhaust system???? Original owner of 87 IROC-Z and mine rusted and fell off after five years. Also nothing special about the system.

The iroc-z should only have 1 cat, and your 91 should have 2 cats. So now they will not bolt up. Also listen to the post above. I only paid $325 for my flowmaster american thunder installed on my 91.
