Would a fmf q4 be louder or quiter than a stock pipe on 2012 yz450. I never though I would consider buying a pipe for it cause I don't need more power and I like not having bike that obnoxiously loud for the occasional trail ride even thoug I do race mx but I would consider one if it was around the same db level as stock pipe. I would be interested in a pipe that would kind of broadin or smooth the power out but don't want one that's excessively louder than stock. Other option would be be stay stock and get gytr tuner. I could also not do any thing since I have no huge complaints as is but every body likes tinkering at least I do. Any advice experience thanks guys.
