Depends, I had called the dealership monday. I had been rear-ended on sunday, so i was pricing out a bumper. I have an SLT. But I wanted to buy the sport bumper and do a dualie exhaust. So I asked him about that. and he said cat back no problem. but once you cut the exhaust cat back, its voided? but not cat to headers? i dunno , But because of the o2 censors and whatnot its a very grey area. i'd call to make sure.
