Exhaust valve simulator for removing your exhaust valve actuator  or you can also disconnect the valve actuator in the open position on your stock exhaust to operate in the full open position all the time.  Simulator simply plugs into the wiring harness that goes to the muffler exhaust valves and eliminates the soft error code and cel that appears when the valve is removed/disabled.

These are made in the USA and each one is bench tested to ensure correct valve cloning  before shipping.  Electrical components are embedded in 3M potting epoxy making them completely sealed from moisture , dirt, and debris.

Includes protective plug for actuator.
