Universally recognized as the most desirable silencer configuration for supercross and tight stadium-style performance, the Shorty is engineered to alter backpressure for an immediate response. By shortening the overall length of both the aluminum canister and its internal perforated core, FMF effectively optimizes exhaust scavenging to significantly improve the hard low-to-mid range power hit of your mini racer.\u003c\/p\u003e\n\u003cp\u003eBuilt to handle rigorous off-road racing conditions, this premium slip-on muffler features a lightweight oval aluminum canister mated to a rugged stainless steel mid-pipe and a sleek conical end cap. It strips away top-heavy rear weight compared to bulky stock factory mufflers, noticeably enhancing cornering agility. Whether you are attacking technical indoor tracks or looking to jump out of deep loam ruts faster, this bolt-on silencer delivers the crisp, aggressive two-stroke power snap that puts riders at the front of the pack.\u003c\/p\u003e\n\u003ch3\u003eTop Features: FMF Powercore 2 Shorty Silencer\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShortened Canister Architecture:\u003c\/strong\u003e Decreases internal volume to accelerate exhaust gas pulse velocity, maximizing bottom-end snap and acceleration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight Oval Aluminum Body:\u003c\/strong\u003e Considerably reduces vehicle mass relative to OEM silencers, optimizing handling dynamics and weight distribution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrack-Proven Core Tuning:\u003c\/strong\u003e High-flow internal perforated core layout maximizes power transfer across competitive racing environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Stainless Steel Components:\u003c\/strong\u003e Heavy-duty mounting brackets and premium inlet pipe construction ensure longevity against flying track roost.\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\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;\"\u003e2003-2016\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e85 SX\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;\"\u003e2017\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e85 SX (17\/14)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2008-2009\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e85 XC\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;\"\u003e2007-2012\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e105 SX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2007-2012\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e105 XC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the primary difference in performance between the FMF Shorty and a standard Powercore 2 silencer?\u003c\/strong\u003e\u003cbr\u003eA: The standard Powercore 2 offers a broad, evenly distributed powerband boost across all RPM ranges. The Shorty silencer condenses that exhaust resonance to specifically target and intensify the immediate bottom-end power delivery, providing a much sharper and punchier throttle response when exiting corners.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should I rebuild and service the internal packing of this FMF Shorty silencer?\u003c\/strong\u003e\u003cbr\u003eA: Because shorty models feature less overall volume, the packing material inside gets saturated with unburnt two-stroke oil slightly faster. We highly recommend extracting the end cap and repacking the core with fresh fiberglass filler every 15 to 25 hours of operation to prevent power drops and excessive bark.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing a high-performance two-stroke silencer, avoid reusing an old, degraded rubber pipe-to-silencer coupler sleeve. A worn joint allows unburnt oil (spooge) and exhaust gases to bleed out, which ruins your subframe finish and disrupts critical internal wave pressure cycles. Always replace it with a fresh silicone sleeve coupler and seal the dry joints with a thin film of high-temperature RTV silicone for optimal performance results.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/new-ktm-85-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 85 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-2-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eKTM 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.
