The motor is good all over the power band, best $200 you will ever spend on a motor. The 2013 pipe is the best but it is 1/2 as much as the motor The Thunder Tiger 2050 AXE 2060 and even the Dynimite or Ofna 086 will work. I have driven this motor in about 5 cars and Truggies in Arizona and they all rip. My friend Chris just hit the 6 gallon mark on his and it stiil runs like new. If you can give up a little fuel mi. Try the JP1 yes I said JP1. the motor likes this pipe ALOT.
