Make a post in the
http://www.duramaxforum.com/forum/vendor-price-request/ section with what you want and they will get with you. If you are still doing some research some of the tuners i would look at is: ATS, Quadzilla, PPE, and Diablo. For exhaust i would 4" turbo back and there are several differnt good brands. The intake is not all that important until you get closer to the 500 hp mark, but if you want one look at AFE, Banks, S&B, and Volant.
