I just installed an afe stage 2 and juice w/attitude in my 2006 qc 3500 drw. I'm thinking about having the local exhaust shop replace the muffler & cat with raw pipe. Or maybe put a MBRP muffler in place of the cat & raw pipe to replace the factory muffler. I'm pulling a 3 car trailer (25,950 gross weight) and I'm concerned about egt's. would like to get them down and maybe pick up a little power & mpg and better sound. Whatever I do I need to be able to bolt the factory stuff back in place on the side of the road in case of warranty work. So if I'm 3 states away hauling cars and have a problem I can ditch the trailer, pull off all the perf stuff and pay a visit to the dealer. Sounds like a hassle but I've done it before, just never with the exhaust. So if I can just replace the cat & muffler, I can carry the factory ones with me which would be better than bringing the whole cat back.
Anybody running a straight - thru exhaust on the 04. 5+ ???
