For 428i 2.0l Turbo models with 180 kW the rear silencer can be mounted on their own. No adaptor is needed in order to mount the rear silencer! For 420i 2.0l Turbo models with 120 kW or 135 kW only the complete exhaust system can be mounted! For models without a standard M-rear apron, we recommend using the original BMW 435i rear apron with cut out for 1x tailpipe LH+RH when mounting the rear silencer BMWF30-Q90R(S) or BMWF30-K/Q90R/C. For vehicles with a standard M-rear apron we recommend using the rear valance insert BMWF32-HE1 or BMWF32-HE2 when mounting the rear silencer BMWF30-Q… or BMWF30-K/Q…

Using the remote control AG/FB-EP, the exhaust flap can be opened manually. It will be opened permanently afterwards. Not permitted in public road traffic! The remote control is included when purchasing the rear silencers with exhaust flap!
Function of the valve control:
A special control unit monitors the vehicle’s speed If the speed exceeds a fixed value (70 km/h), the exhaust flap’s servomotor receives a signal to open. The exhaust gas flow is then bypassed and you get a different sound. If the speed of the vehicle drops below the fixed value (70 km/h), the exhaust flap closes again automatically.
