Whenever you install a high-performance exhaust system that increases airflow, you should adjust your jetting to match the new power characteristics and prevent a lean condition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this pipe compatible with the stock silencer?\u003c\/strong\u003e\u003cbr\u003eA: While it may fit, the Factory Fatty is designed to work best as a complete system with FMF silencers. We recommend pairing it with an FMF PowerCore 2 or Shorty silencer for peak performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing your new FMF pipe, always use a fresh exhaust O-ring and a high-temp silicone sealant at the flange. A leaky connection kills the pressure wave your 2-stroke needs to build power, and it will quickly ruin your new pipe's finish by spraying unburnt premix oil all over the header.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz85-performance-parts-and-accessories-moto-house-mx\"\u003eYamaha YZ85 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-2-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 2-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Maintenance \u0026amp; Motorcycle Tools\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eAbout Moto-House MX\u003c\/h2\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
