Big Mack Truck Posted March 18, 2022 Share Posted March 18, 2022 I recently discovered 07 Mack pinnacle came with an MP7 and it doesn’t have a DPF on it. I was curious to know if I could take an 04 epa MP7 and give it the upgraded piston design and cherry pick from the list of improvements they’ve made over the life of the engine minus the dpf/def. if this is possible, who would you recommend to speak with?
