Exhaust system for the Mercedes SL500 R231, with valves, T309 stainless polished; includes programmable valve controller CES-3.
This valve controlled exhaust system fits on the Mercedes SL500 (type R231, manufactured since 2012) and gives it a extremly powerful sound. The whole system is made of T309 heat resisting stainless steel. The connections are compatible with the original Mercedes pipes.
With use of the control unit CES-3, the system is freely adjustable and backpressure-controlled. The control unit gives you the ability to adjust the pressure you want to drive. In this way you can get the maximum available power. Pressure behavior which costs power will be regulated out.
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 features an illuminated display showing all functions in plain text in 3 different languages (German, English and Italian) and 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 stainless steel (close to Inconel properties) throughout the entire system and the entire system is then hand polished to a mirror finish.
