This pipe brings that same professional-grade craftsmanship and material quality to your Beta 250 RR or 300 RR, effectively broadening and smoothing out your power curve. By providing substantial gains across the entire RPM range—including stronger low-end, improved mid-range, and increased over-rev—the Fatty is the premier choice for riders seeking versatile performance in any riding environment.\u003c\/p\u003e\n\n\u003cp\u003eEngineered for both performance and durability, this pipe uses lightweight 20-gauge steel for the main body to reduce mass, while the header section is reinforced with 19-gauge steel to better withstand the rigors of off-road and enduro racing. The precision hand-pounded seams ensure smooth, unrestricted exhaust flow, eliminating turbulence to maximize your Beta engine's power output.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: FMF Factory Fatty Pipe\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003eRace-proven design modeled after authentic factory \"works\" cone pipes\u003c\/li\u003e\n  \u003cli\u003eEnhanced power delivery across the entire RPM range\u003c\/li\u003e\n  \u003cli\u003eLightweight 20-gauge steel body with 19-gauge steel header reinforcement\u003c\/li\u003e\n  \u003cli\u003eHand-pounded seams for optimized exhaust gas flow efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease review the detailed compatibility data below to ensure an exact fitment match for your motorcycle before finalizing your purchase.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eFitment List\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #e0e0e0; margin-top: 15px; margin-bottom: 15px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f7f7f7;\"\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eYear Range\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Brand\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Model \u0026amp; Sub-Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2013-2019\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e250 RR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2013-2019\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e300 RR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this pipe offer more bottom-end power than the stock Beta pipe?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, the Factory Fatty is specifically tuned to improve low-end grunt, which is highly beneficial for technical enduro riding, while also extending your mid-range and over-rev.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this pipe compatible with the stock silencer?\u003c\/strong\u003e\u003cbr\u003e\nA: The Factory Fatty is designed to work well with your stock silencer, but for the best results, many riders pair it with an FMF performance silencer to match the flow characteristics.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Beta two-strokes are very sensitive to pipe fitment. When installing your new FMF pipe, ensure the mounting bolts are tightened evenly to avoid pre-loading the pipe, which can cause vibration-related cracks over time. A little anti-seize on the flange bolts also goes a long way for future maintenance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/beta-2-stroke-dirt-bikes-shop-premium-dirt-bike-parts-moto-house-mx\"\u003eBeta 2-Stroke Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/beta-250-rr-performance-parts-and-accessories-moto-house-mx-1\"\u003eBeta 250 RR Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/beta-300-rr-performance-parts-and-accessories-moto-house-mx\"\u003eBeta 300 RR Performance Parts\u003c\/a\u003e\u003c\/p\u003e\n\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.
