The Capristo CES-3 Programmable Exhaust Remote Kit is fully programmable and designed to control the proprietary Capristo exhaust valves installed on every Capristo exhaust system. The control unit continuously monitors exhaust back-pressure, opening the butterfly valves at a preset threshold during acceleration to increase exhaust flow and volume, improving power output, while allowing increased backpressure at low throttle and rpm for improved engine torque and drivability. The kit includes a remote key fob (444 MHz), vacuum solenoid, and a pre-wired harness that only requires power and ground to complete a seamless installation. It features an on-board self-learning function to program additional key fobs and a failsafe that leaves the valves open in case of electrical or vacuum failure - protecting the engine from potential damage. Three valve control modes are available: Cruise Mode — valves only open at higher exhaust pressure for a quieter, more comfortable drive. Sport Mode — valves open sooner under load for a more aggressive exhaust note and increased performance. Open Mode — valves remain fully open, optimized for track-use or when maximum volume is desired. User has the ability to save their default setting without the need to select modes upon every start.
