Questions & Answers

  • My 2006 CFR 250R has dual exhaust and very loud. Will the FMF Q4 slip directly into the header and fit? I would pull the dual exhaust and the pipes that split coming out of header.

    By: Steve K

    Provided the header you're referring to is the OEM Honda header, then yes - the FMF Q4 will slip directly onto the header. It would replace the split coming from the OEM header and you'd go from a dual-muffler configuration to a single muffler exhaust.

  • Would this fit an ssr125 header?

    If not what US Forestry Dept Approved fmf pipe would?

    By: Nate

    FMF Q4 mufflers are designed only to fit motorcycles and ATVs equipped with a stock or an FMF header. In that light, if the OEM muffler fits the SSR header that you have, then there's a good chance the FMF Q4 will also fit. Otherwise, if the SSR header came as a kit with its own muffler, or is designated only to fit SSR mufflers, then this, or any other muffler we sell, is not going to fit your needs - you'd have to source the correct muffler from SSR.
