| The LMM Dmax is much more efficienct with the DPF removed! At 70mph on a straight trip I averaged 20.2 mpg calculated. The DIC showed 21.3-21.5 (inaccurate!) This is with stock tires/wheels.
As far as emmisions/inspections are concerned, be ready to find a small repair shop willing to overlook the minor details when inspecting...
Tyler with meyerperformance has a nice little MBRP exhaust package with the Quadzilla Stealth 2 for DPF delete.
