4" Turbo Back Exhaust
I just wanted to write in and say that I just put in my 4" AFE exhaust system and WOW! Its a straight pipe system that took about 4 hours to install (including removal of the old one). I dont think thats too bad considering my lack of experience, but whatever its in now and that turbo is loving it. The Airaid Intake System, Bully Dog 6 Pos Chip, and the AFE exhaust combo definitely make that truck run a lot different than it did when it was stock. I dont think I would have done it with out reading a lot of the threads on this forum, so thanks for all the advice you forum veterans throw out to us new guys. It may not be the system that a lot of you would have picked... but it fit my bill and I'll keep everyone posted on the fuel mileage improvements.
