No idea about fuel economy and haven't dyno'd my 3W. So no empirical evidence. But I can state unequivocally that my 3W runs the rev range quicker and has more pulling power at low revs than it did before the baflectomy and stealth intake. Where the pipes used to glow bright red, this is no longer the case. The engine feels happier and runs smoother so I'm easier on the throttle. Does that result in better fuel economy? Dunno.
