These seems like an Evolve or similar catted-x pipe situation, with cats still in the secondary position and resonators

I have the AFE, and I like it, mainly because still have no CEL after what like 4,000 miles on it, but my personal opinion is it would still be pretty loud with the stock back box, and fit like crap, because I had to adjust the slip joints at the MPE muffler to get it to line up right. But that's just like, my opinion man. I wouldn't recommend this xPipe UNLESS you want to keep O2 monitoring readiness unaffected, in which case, you at least have a decent chance as I did.
