DPF removal
Does removing the DPF but leaving the cat on increase fuel economy on a six pot diesel engine? Or are the manufacturers of these pipes bulling them up?

mapping the car yes, in the way that car would use much more of its power/torque and wont shift as much from high gears back to low, specially on hilly roads. - thats for performance/economy map
As for removing the DPF I do not believe that the fuel economy increase would be significant enough to justify it? - could be wrong on this one, maybe Antti could gave us some details/numbers
