I have a 2003 duramax 2500 with 235000 miles on it. New turbo and injectors as of 35000 miles ago and now im looking to put some new larger exhaust on it and a new air intake:thumb:. I was looking at mbrp 5" straight pipe with no catalytic or muffler...and maybe a banks cold air set up. But before i spend the money on these i wanted your guys opinion to see if i could maybe get something a lil better, or if i should spend the money on something else now to save me money in the long run if something were to break. Thanks for all the help guys:thumb:
