GYTR® Oval Aluminum Muffler
GYTR® exhaust systems feature a pipe diameter that increases in steps from front-to-back. This stepped design gives an engine with our GYTR® exhaust system a clean response off-throttle, a major increase in low-end power without sacrificing any midrange and also improved power on the top.
Features include:
  • Ball-burnished, 6061-T6 aluminum end caps
  • Ball-burnished, stainless steel mounting strap and bands
  • Aluminum shell with stainless steel inlet pipe
  • Silent Sport™ pillow packing
  • Removable, screen-type USFS-approved spark arrestor
  • Completely rebuildable
