CAPRISTO REMOTE EXHAUST VALVE KIT

This onboard remote control kit allows you to open your exhaust valves at the touch of a button.

The purpose of controlling exhaust back pressure is to achieve better engine torque and maintain driveability in a wide range of conditions. Today’s high-performance engines prefer a free-flowing exhaust at wide throttle openings and high RPM. At smaller throttle openings and low RPM, such as those encountered in traffic, a slight increase in exhaust back pressure results in better low-end torque and a more user-friendly engine.

This pressure is controlled by one or a set of butterfly valves in the exhaust system. These valves are controlled by the engine ECU, which opens and closes them according to a preset set of rules. When using the vehicle on a track or in a sporty environment where it is desirable to keep the valves open, a push of a button on the remote controller makes this possible.

This controller interfaces perfectly with your exhaust valve-equipped Capristo or OEM exhaust for Ferrari and Lamborghini. The electrical connections from your original wiring harness power the controller, making the fitment of this controller as easy as ‘plug and play’. For other makes and models, the harness can be modified or spliced to work with your OEM valve control.

The remote key fob supplied with the controller is stylish and pre-programmed. An onboard self-learning function allows you to program more key fobs if needed. An added safety feature is a fail-safe condition that allows the exhaust valves to go to the open position in case of electrical or vacuum failure, preventing engine or header damage from excessive heat build-up.

The supplied wiring harness comes with both long and short reach options and can be used for single or dual exhaust valve operation.

The kit includes two cables: one 34-inch cable and one 80-inch cable.
