We spent hours, track and dyno testing, perfecting the best pipe for your YZ450F. Designed to come off the throttle clean and improve the low-end grunt, then mellow the mid-range hit, providing controllable power that still has lots of pull. The top pumps out more power than stock, with more over-rev. Hard-anodized aluminum muffler shell with your choice of stainless steel or titanium tubing. Features an all new cone-style outlet cap and inlet cone to keep the muffler as forward as possible for centralized mass. Meets AMA 102 dB requirements. Completely rebuildable. Head pipe uses the stock heat shield.
