I installed a 4" turbo back exhaust with stock cat from mbrp. Took me 3.5 hrs solo with a few minor scratches. Just want to say the whistle sounds great :Thumbup: with the 03 turbo. Now it time to choose programmer.

Yeah, if you think it whistles good now, dump the cat and then have a listen! My MBRP system was the first mod I did to my truck too... Its all downhill for you now bro. It never ends! Good luck with your programmer search, I've only got 3 little letters for you... S C T !!!

I had my motor studded/gaskets replaced proactively. I never blew them first, but its true people have with or without programming. I know a guy with an '05 runs innovative's Xtreme files daily with water/meth and/or a 50 shot of NOS with stock bolts and no problems after 65000 miles... Another friend with an '04 completely stock puked them after about 40000 miles recently. Some go some blow.

Lose the cat. Youll run a little lower EGT, and it will sound even better!
