I have decided on a dpf-r 4.0 to delete the dpf on my 08 for longevity reasons. I'm trying to decide between the doc/dpf delete pipes or the dpf only pipe. My thinking for dpf only is that I'd only be dealing with one sensor instead of 3 or 4 and that it may be easier to change back for resale purposes. I'm not looking for performance gains or a "better" sound, I just don't want it to regen. Pros, cons for one versus the other? Thanks
