I drive an '08 F-350 6.4, 4 door, long bed, 6 speed manual, 4x4. It just broke 100,000 miles the other day and I was looking to do the emissions delete kits, but I'm not sure what a fair price for a DPF delete kit is. A performance shop here in town quoted me $1,475 for a DPF delete, EGR block plates, a high-flow muffler and an H&S tuner. It seems to me like a pretty fair deal because Texas diesel power quoted me $2,100 for just a DPF pipe delete, hollowed muffler, hollowed cats, and no tuner. I need some feedback please.
