Over time, internal two-stroke oil and unburnt fuel will saturate the packing material, resulting in power loss and a louder exhaust note. We recommend removing the end cap screws and replacing the internal fiberglass packing every 20-30 hours of hard track operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I run this slip-on muffler with my stock factory Yamaha expansion chamber pipe?\u003c\/strong\u003e\u003cbr\u003eA: Yes, FMF designs this slip-on unit to be fully compatible with either your original factory expansion chamber or any corresponding performance FMF expansion pipe (such as the FMF Fatty or Gnarly series).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When slipping your new FMF silencer over the header pipe connection joint, never rely solely on a dry metal-to-metal connection. Apply a thin, consistent bead of high-temperature silicone sealant (such as Permatex Red or copper RTV) right around the slip joint inlet. This tiny seal blocks dangerous micro air leaks that draw cool outside air into the system, which can cause erratic low-end lean bogging and annoying black exhaust splatters on your swingarm.\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\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eMotorcycle Chemicals\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
