I have had 2 duramax's and love them. Never a problem. I need another one to add to business. So im stuck on a GMC 2500 Denali 4x4. Probably going to get tomorrow or thursday. I will still use other one for heavy work and to beat on. So what is the stuff you have to pour in for exhaust cleaning on these? My buddy has one and said its a pita and he is waiting for someone to make a delete kit for it.
