Yoshimura RS-12 Slip-On Exhaust for the 2024–2025 KTM EXC-F and Husqvarna FE Models

Power increases were massive with this one! The KTM500 EXC-F responded to the Yoshimura RS-12 Enduro Series Slip-on like a dream, adding 20% max HP and 8.2% max ft-lb of torque. These are extraordinary numbers for a slip-on exhaust system, and they’re achieved even with the pre-installed spark arrestor!

• Max Horsepower Increase: + 20%
• Max Torque Increase: + 8.2%
• Experience dramatic improvements in acceleration and overall engine performance.
• Compliance and Performance: Maintain regulatory compliance with the spark arrestor while still enjoying giant power gains.

• Design Optimization: RS-12 provides ample clearance for the brake caliper, ensuring no interference with braking components.
