What year and motor?When doing a change-over to conventional exhaust, does one have to do a def delete, if so,how ?
I have a 2011 6.7. I did a complete delete. If you remove DPF you will need a tuner. From before deletes to after, complete different acting truck. So much power its insane. You can find complete kits on Ebay. I went with a Mini Maxx tuner, Sinister EGR delete kit, S&B cold air intake and FLo Pro 5" Stainless exhaust. Cost me $1600.00. Did it in my driveway over a weekends time. Highly recommend.
