We highly recommend checking your jetting to ensure your engine runs optimally.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this pipe come with the silencer?\u003c\/strong\u003e\u003cbr\u003eA: No, this is for the expansion chamber only. However, the Factory Fatty works perfectly with the stock silencer or an FMF performance silencer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing a new pipe, always use a fresh exhaust gasket and high-temp silicone sealant. A slight air leak at the flange will cause your bike to run lean and can quickly lead to top-end damage on a 125cc engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\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 \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/unlock-peak-performance-for-your-yamaha-yz125-high-quality-parts-accessories\"\u003eYamaha YZ125 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003ePremium Motorcycle Chemicals \u0026amp; Maintenance\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.
