How's it going everyone? Noob question here. I am trying to order a cat-back exhaust for my 14 R/T. For the R/T, Magnaflow and Borla have 2.5 in., but I want/need to go to a full 3 in. exhaust. If you look under the SRT on the same sites, they are all 3 in. So, are the R/T and the SRT exhaust systems completely the same or what trouble will I run into trying to put the 3 in. onto a 2014 Challenger R/T?
