B BadBoy Advanced Member Messages 179 Jul 12, 2006 #1 I know that the ideal pipe diameter is 60mm but have also been told that a 57mm bore is fine for n/a. Also the BC pro spec is > 60mm does this mean that power low down and mid range will be poor? Any comments or suggestions on this?

I thought the more backpressure the better the torque and low down and bigger bores affect the high end and sacrifice low down..
