This OEM Exhaust Control Flap is a critical component of the power valve system in modern 300cc TBI engines. It regulates exhaust port timing to optimize power delivery across the entire RPM range, ensuring smooth throttle response and peak engine performance. As an authentic factory part, it guarantees precise fitment and reliable operation under extreme heat and pressure.

Compatible with a wide range of 300cc models including: KTM 300 EXC, SX, XC, and XC-W (including Six Days, HardEnduro, and Champion Editions) from 2023-2026; Husqvarna TE 300, TX 300, and TC 300 (including Pro and Heritage models) from 2023-2026; and GasGas EC 300, EX 300, and MC 300 (including GP models) from 2024-2026.

Constructed from high-grade materials, this flap is designed to withstand extreme exhaust temperatures and resist carbon buildup. Replacing a worn or sticking flap is essential for restoring lost bottom-end torque and preventing erratic engine behavior. This component is vital for maintaining the sophisticated exhaust timing required by fuel-injected two-stroke engines.
