I have the kit on my 07 xrs and I gotta say what a difference. I am so impressed with slp on this kit. For under a $1000 I doubt you will find better bang for your buck. If I were you I would'nt hesitate on getting the kit for your xp.
Hey T/A, can you use the pipe with an HPS can, or do you have to run the SLP can with the SLP pipe? Also, if I already cut my head, do you have to run the SLP one? I'm curious if you can just run just the pipe, or if they want you to buy the whole package to make it work as advertised.
