I have removed the dpf on my 2006 330d 2 weeks ago and installed an ecotune pipe with a remap, I carried out the work myself although the actually removing the dpf it self was a right pita! fitting the replacement ecotune pipe was a breeze, but I must say since the dpf removal its running really well with improved pedal response and mpg and very happy with the results, my next delete will be the swirl flaps and egr which i'm hoping to do in the next few weeks.
