MAC usually has a problem with fitment so im gonna venture to say they will rub. and dont get the 3" exhaust. its pointless for you to do that. wont sound different and you are actually losing horsepower. So i would say just get the 2.5" catback with the 3.5" tips and that will be your best bet with an o/r x pipe. that thing will sound crazy good!!!

^^^^ He's right about losing power.

I had a fullsize Chevy (YUCK RIGHT) and decided that I was really gonna open it up despite what the muffler shop told me. Well I should have listened. I put too bigger pipes on it and it sounded great, but I definately lost bottom end.
