Simons sports rear silencer for BMW 3 Series and 4 Series with 320i, 330i, 420i and 430i engine. The system fits F30, F31, F32, F33 and F36 models from 07/2015-2019 and is supplied as a stainless steel rear silencer with outlets on both sides.
The rear silencer is made from stainless steel with 76 millimetre pipework, which splits into 2 x 63.5 millimetres towards the rear silencer. The system has duplex 4 x 80 millimetre tailpipes and gives the car a significantly sportier rear appearance.
The larger pipework provides a more open flow than a standard exhaust system and can help reduce back pressure on the turbo engine. The sound becomes deeper and sportier than original.
The system fits both with and without xDrive. The bumper or diffuser must be modified or replaced, so there is correct clearance for the four tailpipes.
