I'm contemplating adding a 4" turbo back exhaust on my 99 7.3 diesel. I have a mild DP Tune and the Ford AIS air intake opened up for additional airflow. The MBRP seems to be pretty well thought of. They have aluminumized steel and stainless versions, the aluminum versions hundreds less which is the direction I was thinking as exhausts seems to last forever here in the desert. Hoping for a little more performance and to keep the EGTs low although I'm doing fine on both accounts right now but more is better, well not egt. Any recommendations or experiences?
