I purchased an 87 Banshee a couple years ago and have learned alot from this site. I mostly use my bike for trail riding and jus riding around at my farm, and I believe that it has stock yamaha pipes. What I was wondering is I looked at the FMF Turbinecore II Q kinda liked them because they are supposed to be quiet. But everywhere I look it says that it must be used with FMF pipes. Is this true, and if so is there a aftermarket silencer I can purchase for the stock pipes??
