440 Pro X Variable Exhaust System:
The exhaust valve system on the new 440 Pro X is electronically controlled by solenoids. Pressure from
the cylinders is routed through the solenoids to the atmosphere. During this time the exhaust valves are
down. When the CDI senses 6700 RPM, it triggers the solenoids to shut off the bypassed air going to the
atmosphere. Pressure then builds inside the exhaust valve bellows, causing the valves to fully open.
When RPM drops below 6700, the solenoids open to allow air to bypass through to atmosphere and the
exhaust valves close.
