They are good pipes also, i would choose the pipe based on which cam and timing you have and what kind of power you want, low end or top end. Some pipes make better power down low and some make better power on top, just depends on the size and stages i believe. I can tell a noticeable difference between an .880 RLV pipe i started out with and the Holy Moses, the HM pipe has better torque on the low end and better power on top end also. Have not been on the track yet with the candy cane, but it sounds like it is gonna be a little better than the Holy Moses in my opinion.
