Hmmm, for the N54 the JB4 comes with DPfix. For the N55 it doesn't?

they're both reputable companies - fitment is good, performance is a +. The DPs for the N55 have done their job eliminating the set of cats on the 335i models. u'll be good with whatever you choose. good luck with the new power mod.
