Manual Switch Hydraulic Exhaust Valve (Weld-On, Waterproof)

Fine-tune your motorcycle’s exhaust note and back-pressure with this manual-switch, hydraulic-pressure exhaust control valve. The weld-on stainless body sits in-line with your mid-pipe; a bar-mount manual switch drives the hydraulic actuator to open/close the butterfly, letting you go from quiet stealth to freer flow in seconds. The actuator housing is sealed for rain-ride durability, and the valve shaft uses high-temp seals for reliable operation.

Use cases: early-morning starts, city commutes, long-ride fatigue reduction, or opening up flow for track days.
Installation: welding required—professional fitment recommended.
