I ordered a delete kit with mini maxx, EGR delete, and 5" MBRP exhaust. We had a little confusion on both ends. I emailed them Friday. Chris called me Monday and cleared up the confusion. I will definitely do business with them again. Thanks again Chris.

Very happy with Diesel Ops service. My order was delivered on time. I had a couple questions about installation. They had a tech guy who was great help and easy to talk too. I would recommend Diesel Ops to anyone!
