I've heard that the PC pipe is for mid to top end. My question is will it kill the low end? The whole reason I got the KX is for it's low end grunt while woods riding. I've read that the Gnarly is for low end, but after talking to 3 different people that I know they have all caved in their FMF pipes while trail riding. I beat the crap out of my PC pipe on my old KX125 and it held up great. I read a review of the pipe on the KX in a mag and they said it didn't hurt and may have even helped the low end and was an awesome improvement for the mid and top but curious to those who have done it on here what their results were..........Thanks
