Handcrafted exhaustsystem with valve flaps for Audi RS4 / RS5
The exhaust is handcrafted of 1.4828 stainless steel exceptionel in Germany on order and contains 2 valve flaps. Controlling the flaps is either done with our control unit or with the oem control.
Through intelligent construction the weight is reduced about 50%
Exhaustsystems by Wheelsandmore – perfect fitment without additional work as welding or cutting and developed on latest dyno to achieve a perfect power increasement.
Power increasement= 15hp / 10NM

Function of the back pressure monitoring control unit for remote controlled exhaust valve flaps
Freely program-able ECM-2 control with back pressure monitoring, two shapely remote controls, connection cable, solenoid valve and vacuum hoses
Article number control unit ECM-2: 04AZ00703003
Article number hand transmitter: 04AZ00703001
Suitable only for connection to vacuum-controlled exhaust flaps
Functionality:
Dynamic pressure monitoring control with freely program-able parameters. The control can be freely configured to open the flaps at the desired time when reaching the set back pressure value. As a result, the maximum possible engine power is generated because power-reducing back pressure can be avoided. This control combines all advantages in both low and high speed ranges, as the back pressure can be set exactly for maximum engine power.
All information regarding the current flap status is sent to the car radio via Bluetooth / RDS and can be called up in the radio display. The remote control remains fully intact.
The switching modes:
Button 1) In travel mode the exhaust flaps open late or at full throttle
Button 2) In sports mode, the exhaust flaps open earlier or at full throttle
Button 4) In open mode, the exhaust flaps are permanently open
Advantage of back pressure monitoring:
Most damper controlled exhaust systems open the valves either rpm or speed dependent. However, since the engine power does not depend on speed or rpm, but on the back pressure, we achieve the maximum performance with our control unit in combination with perfectly constructed pipe diameters and ducts for all our exhaust systems, which are measured on a state-of-the-art dyno test.
Another major advantage of the controller is that it recognizes the driving style of the driver and opens the flaps even earlier at aggressive full throttle.
