FMF is the big name in pipes and their mini pipes rock! This is a good pipe for a closer to stock XR/CRF50 with a few other engine modifications. We offer other exhausts that will flow a bit better for the more aggressive stroker 108cc builds and other larger full tilt style 50 builds.


  • CRF/XR 50 - 2000-Present


  • OD at header - 21.8mm
  • ID at header - 18.5mm
