Well I finally made up my mind and found a really nice 2004 YZ250 last weekend. I am mainly going to be using the bike to trail ride and chase my son around on his TTR125L. He is hoping to upgrade to a YZ125 this summer but I am not sure if I am going to let him. My question is, my bike came with a PC Platinum 2 pipe and a R304 factory sound silencer. For riding in the woods up north I need a silencer with a spark arrester. I have heard nothing but good things on the FMF Q Stealth. Can a run that silencer with my PC pipe? Should I put the stock pipe back on? Or should I look at a PC nature friendly silencer? Thanks for your help.
