The short answer is, yes. Doing a DPF delete will void your warranty. The long and more realistic answer is, it depends. It really is a case by case basis and comes down to the dealer your working with. Every dealer knows that the diesel particulate filter causes major issues and is only there to appease the EPA and there federal mandates. They also want to get paid by the manufacture for performing warranty work. So we suggest getting in contact with the dealer your interested in taking your truck to and pose some hypothetical questions. Pick there brain and see if there a DPF delete friendly dealership. Of course were bias on the topic, but to be frank. The primary reason you need a warranty is because of all the emission components that have been added. Our advice... delete the DPF as soon as possible.
