This \"corked\" feeling results in sluggish throttle response and a lack of the raw grunt needed to loft the front wheel over logs or power through deep sand. The Yoshimura RS-12 Full System is the definitive solution, engineered specifically to transform these large-displacement machines into true performance powerhouses.\u003c\/p\u003e\n\u003cp\u003eThe dyno numbers speak for themselves: a massive 21.8% increase in peak horsepower and a 15% boost in peak torque. Built with \"Factory Quality\" precision, the RS-12 features machined joints for a leak-proof seal and an asymmetrical muffler profile that provides maximum clearance for the rear brake caliper and tire. The header and mid-pipe are pushed forward for superior weight centralization, ensuring your Husqvarna FE 501 remains nimble on tight single-track trails while delivering a aggressive, race-ready exhaust note.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eDyno-Proven Gains:\u003c\/b\u003e Dramatic 21.8% HP increase and 15% more torque for tackling technical terrain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFactory Quality Machined Joints:\u003c\/b\u003e Ensures an exacting 360-degree fit for increased system life and durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUSFS Approved Spark Arrester:\u003c\/b\u003e Includes a pre-installed, trail-legal spark arrester for public land riding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight Centralized Design:\u003c\/b\u003e Tapered muffler body moves mass toward the center of the bike for better handling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMatte Carbon Fiber End Cap:\u003c\/b\u003e Features an innovative inner-cap mount for easier servicing and a \"Works\" factory look.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU: \u003c\/strong\u003e\u003cspan class=\"variant-sku h5\"\u003e265000S320\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003ePlease note that because the RS-12 is designed for maximum flow and volume, the muffler outlet sits directly in line with the stock KTM and Husqvarna rear blinkers.
