If you are talking about seeing the tubes curve around the fuel cell, thats because they have to be re-routed for the IRS. The plumbing is just different. Almost any brand cat-back exhaust you can buy will have a disclaimer 'will not fit on Cobra/IRS' etc if its just for a GT. Unless you get a fabricated exhaust, I would think the only way to get the same look is to find and swap a Cobra IRS for your rear suspension. Hope this helps
