I have a Lot of pipes to try with the X2 and i am getting the pipe Axe Rossi recommended i think it is the AXE Rossi 02121. On the Mamba we found the JP2 pipe worked the best and on the Cobra i ran an 053 pipe. How did you like the X2 will you keep running it this year are will you be Moving on to other motors?
Chris, I always start with the JP4, but will swap if I need more torque or high end, just like any other motor. I keep all sizes for tuning.
I can seem to get about 10+ mins with the JP4, and has a smoother mid range, so that is the only reason I start there. If the track allows it, I'll stick with that set up.
I like the motor, it has the power when I need it, and the smoothness to maintain consistent runs. ...and tuned right, really good fuel mileage.
