Mine was done last year. I get about 5 MPG better when towing, even more when not towing. Engine brake is better, more HP and actually runs cleaner if you don't romp on it all the time, which I don't. In addition to DPF delete, I also did EGR, which means no exhaust gas recirculating into the motor. That stuff will really foul your oil, rings, etc. Motor is much cleaner now, more power, more MPG and will last much longer without being choked out all the time. Oh, did I mention it actually runs CLEANER when not being romped on?
