The iconic CAPRISTO Valved Exhaust System offers the best of both worlds through its capability to produce an aggressive exhaust note under acceleration, and a more subdued sound for city driving.
This feature is possible using vacuum-actuated valve flaps that open and close depending on driving conditions and input from the driver. At lower engine speeds and during cruise operation the valves are closed and produce a deeper exhaust note. At wide-open throttle, the valves open releasing the full symphony of the engine.
The exhaust valves are backpressure-controlled and user programmable via the included CES-3 Control Module. The programmable control unit provides 3 modes operated via a remote key fob:
Cruise Exhaust valves open at higher RPMs
Sport Exhaust valves open at lower RPMs and hard acceleration
Open Exhaust Valves Remain Open
Both the Cruise and Sport mode can be individually programmed for specific backpressure allowances to determine when the exhaust valves open. This allows precise control of the exhaust based on the drivers personal tastes and tolerance.
