As of now, I am running the Roush axle backs and I am happy with them, but I keep throwing around the idea of getting a lethal x pipe and going back to stock mufflers. I am going to order a SFT tuner soon and will probably run the MPT ghost cam tune. Now I know the better setup for the tune is to run the catless xpipe but with my Roush axlebacks that would be annoying as ****. Should I go back to stock with the xpipe and eventually put gt500 mufflers back on or keep the Roush's and throwout the idea of the pipe?
