I'm looking to purchase an 07 2500 with the 6.7. Here is my concern. As it sits with 180k miles, the DPF, EGR VALVE, AND EGR COOLER are all removed from the truck. There is a place where the valve used to be, and in place of the DPF they ran a straight pipe. Not sure if it's modifications would scare somebody or should scare me away from this or if it really doesn't make that big of a difference

 

Do you live in a place where you need emissions? If not, those deletes have actually helped the truck (I would put a muffler on it rather than straight pipe though).
