I've got a Saleen rear bumper on my '00 GT. The problem I have at the moment is that it's almost like the exhaust tips are too far apart to fit in the bumper cutouts. It appears I still have the factory over the axle pipes with flowmaster mufflers welded in. A PO did the work so I don't know if the fitment problem is simply a product of that work, or if it's a common problem with the Saleen bumper.

Is there a certain cat-back I should run to fit the Saleen bumper? I've toyed with the idea of doing either the Flowmaster catback or the Mac Catback. What kind of mufflers does Mac use?

Thanks
