Simons catback sports exhaust for BMW 3 Series and 4 Series with 320i, 328i, 420i and 428i engine. The system fits F30, F31, F32, F33 and F36 models up to 06/2015 and is fitted after the catalytic converter.
The exhaust is made from stainless steel with a 76 millimetre main pipe, which splits into 2 x 63.5 millimetre pipework towards the rear silencers. The system has duplex 2 x 90 millimetre tailpipes, giving the car a more sporty and distinctive rear appearance.
The system fits both with and without xDrive. It is intended for a diffuser/bumper with outlets on both sides, for example a 335/435 diffuser with M Sport package. Does not fit a bumper/diffuser with only one cut-out on the left side, as the outlet is positioned differently and cannot be cut correspondingly on the right side.
