BMW M2 (F87) - Valved Exhaust System with Mid-Pipes & Remote
The exhaust valves are back pressure-controlled and user programmable. A built in limit prevents reaching dangerous pressure levels. There is a control unit for monitoring the back pressure.
This control unit provides the ability to individually program the back pressure one would like to have the valves open or close. The portion of back pressure resulting in a loss of performance is filtered out. This way, one can reach the maximum performance.
This sports exhaust combines all advantages in both the lower and higher range of revolutions (rpm), since the back pressure can be exactly controlled to enable the engine to gain the maximum performance. The programmable control unit provides 3 basic modes to be operated via a remote control, namely:
- Cruise mode - the exhaust gas valves open later
- Sports mode - the exhaust gas valves open earlier
- Open mode - the exhaust gas valves remain open
In both the cruise mode and sport mode, one can individually program when the exhaust gas valves shall open. One big advantage is that the control unit recognizes the driver's operation characteristics. If the driver accelerates aggressively, this is identified by our device by the kind of back pressure that is generated, and the exhaust gas valves open immediately. Usual acceleration results in a later opening of the exhaust gas valves.
Made of high-grade T309 (1.4828) stainless steel (close to Inconel properties) throughout the entire system and the entire system is then hand polished to a mirror finish.
Capristo Automotive emphasizes that you should avoid to rev up your car while not moving! The exhaust flames that may occur could cause damage to vehicles and people in near proximity!
