RENNtech Stainless Steel Valved Sport Exhaust System SLS
SLS AMG Valve Controlled Sport Exhaust System (Incl. Programmable remote control)
Back pressure monitored exhaust system with two exhaust valves for the Mercedes SLS AMG. Made of 1.4828 (T309) stainless steel. Now with German TUV approval.
This exhaust ships with the following parts
- a twin sound valved muffler set
- a secondary cat-delete pipe
- mounting and fitting hardware
- a programmable remote to operate the valves
The muffler is back pressure-controlled and freely programmable.
There is a control unit for monitoring the back pressure. A built in limit prevents reaching dangerous pressure levels. 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. Therefore, 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.
