Like Brian said earlier, it will backfire when engine braking from higher rpm's. I also had read in a tech article that reducing the back pressure also can reduce torque, I don't know how much, as you can see in the second video, no problems accelerating.Oh and thanks for the Sound clips btw Kevin! Now 1 more thing I have to ask, I know this will change sound, but is there any loss in performance by changing the 'breathing' this way??
