Description
RDLN low-mount performance exhaust for 139QMB-based 50cc vintage-style scooters. Designed specifically for bikes with lower cowls (Lowboy, GY50, and similar retro-bodied frames), this system routes the chrome header pipe under the floorboard and positions the black matte canister low and parallel to the frame for a clean, sleek look. Right-side mount. Made in Taiwan by RDLN.

If your 50cc engine code contains "QM" or "FM", this exhaust is likely compatible with your vehicle. Verify your frame has a lower cowl configuration before ordering — this is a low-mount system and will not fit standard upswept exhaust layouts.
Off-road use only. Not intended for use on public roads or land. Check local laws before installing.
