This results in a \"lazy\" throttle response that makes clearing technical trail obstacles harder than it needs to be. The Yoshimura RS-12 Slip-On is the ultimate \"uncorking\" solution, delivering dyno-proven gains of 20% max horsepower and 8.2% max torque—unheard of numbers for a slip-on system—even with the spark arrestor installed.\u003c\/p\u003e\n\u003cp\u003eBuilt with \"Factory Quality\" precision, the RS-12 features an asymmetrical profile that maximizes internal volume while ensuring your KTM 350 EXC-F or Husqvarna FE 350S maintains plenty of clearance for the rear brake caliper during hard landings. The system utilizes Yoshimura’s patent-pending Precision Taper Fit (PTF) insert ring, making it simple to service or swap inserts. Designed and manufactured in the USA, this slip-on centralizes weight to improve the flickability of your machine while providing the deep, aggressive exhaust note these large-displacement bikes deserve.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eMassive Power Increase:\u003c\/b\u003e Delivers a staggering +20% HP and +8.2% torque over the restrictive stock muffler.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFactory Quality Machined Joints:\u003c\/b\u003e Ensures a precise, airtight fit for maximum durability and easy removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePTF Insert System:\u003c\/b\u003e Easy-to-use Precision Taper Fit allows for rapid spark arrestor or sound insert swaps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eIncreased Caliper Clearance:\u003c\/b\u003e Asymmetrical design ensures no interference with rear braking components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUSFS Spark Arrestor:\u003c\/b\u003e Comes pre-installed for immediate, trail-legal performance on public lands.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU: \u003c\/strong\u003e265022S320\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eBecause the RS-12 is designed to maximize exhaust flow on the new 2024+ Austrian chassis, the exit path of the exhaust gases is directly in line with the factory rear turn signals.
