For those who have borla cat-back exhaust once installed to you still have cats or are the pipes straight through and u no longer have cats?
i have the borla cat back system and it replaces from the headers back and the pipes looked like a straight through design. so can some one break it down for me on were the cats are to begin with on the 2011's. i cant seem to see the differnce in the borla x pip and an off road x pipe. im not a huge performance junkie so please take it easy on me
