One can purchase an FMF exhaust system directly from FMF's website, or through another authorized retailer such as MotoSport or JC Motors. It is not recommended to buy an FMF exhaust from a secondary source, due to a lack of warranty coverage.

I need to know the year of your bike to determine that. Once you know that, you can contact an aftermarket manufacturer such as FMF or Pro Circuit and ask to speak with "tech" or "sales" and ask them. Make sure when speaking to them that they think you are interested in purchasing one of their pipes so that they will be interested in helping you.
