I recently picked up a 2005 yamaha banshee, my first two stroke that I've ever owned, I'm working on getting it setup the way I want it for the woods its 100% stock right now I already plan to drop down a tooth on the front sprocket and I was thinking about getting some fmf gnarly pipes to move the power down lower in the rpm range I dont want to run turbine core or power core scilencers because I live in michigan and the sound limit here is 94db instead of the normal 96, usually they will let 96 slide tho also I gotta have a spark arrestor so I was wondering how well the gnarlys will work with stock scilencers or are the Q's worth the money? I dont see them really being that much better than stock but maybe someone can enlighten me
