I got the exhaust put on this weekend and I have to say it was easy and sounds great! After reading a lot about this subject I decided on MBRP 4" turbo back. I got the stock off in 2 pieces, saving the front pipe and cat (just in case). One question, has anyone had thier front pipe hit the torsion bar crossmember? Mine does not vibrate at all and I have not noticed any drone what so ever. Seems to me if they shortened the flange end 1/2" this would not be an issue. Also what direction did you guys install your muffler?

with your turbo back system, did it set a CEL? and is your cat in or out?

Cat is out, I have not set a CEL I have driven the truck for the past 4 days and still have not set one. I have the blocker plate and finger stick sitting here, just have not installed yet.
