I have the straight pipe on right now. Haven't bought the cat yet. I also noticed with the Tanabe that its 60mm and 70mm. My Motordyne is 2.5inch with a 3inch out. Would that mean that the Motordyne flows better because of the bigger diameter pipping used. I read somewhere on another forum that the larger diameter y pipes cause you to lose a little torque down low. Is there any truth to this?
