I just found out yesterday and for those of you who dont know the DPF can be removed. Yes its true, H & S is who you need to talk to. I have not found there website but i found there email and phone number on the Cummins forum. email them at hsperformance@hotmail.com or call 435-669-3709. at the moment your truck will still go into regen but he is testing his mod to stop that and that may be ready next week. but the power agains are 5 - 10 hp and 75- 85 ftlbs. They are hard to get ahold of but they returned my email the next day i was able to talk with them. I figured that i need to get mine cause once the EPA finds out who knows if he will be able to sell them.
