hey yall. right now im running a straight 5inch mbrp exhaust with a 4inch dp cat and muff delete, not much done to the truck just mbrp exhaust and a AFE stage 2 w/ pro gaurd. I see that everyone runs on a 3.5dp. So I was wondering if I should switch to a 3.5dp and run a 4inch exhaust. I heard 5inch exhausts are made for trucks that make 450 to 550hp to the wheel. Would a 3.5dp make a difference on my truck?
