Well my 30,000 mile warranty is going to be done in a few thousand miles. I have had zero trouble w/ my 6.7L since i bought. Was in the shop once w/ check engine light on, but it was due to a recall i had on an O2 sensor. I'm debating on getting an extended warranty or not getting it and spending the money on deleting my DPF and all that other emissions BS....just wanting to get some opinions???

 

well look at it this way anything you plan on doing is it going to void your warranty if so dont bother getting the extended just my oppinion

 

Delete the DPF and block off the EGR!! Your truck will thank you for it

 

Doesn't Cummins still warranty to 100,000 miles? I would get the warranty extended to 7/70 IMHO, simple problems with AC can justify the cost.
