This BMW 435i (F32, F33 and F36) performance exhaust is made in 3"/76.2mm pipework and fits from the turbo to the centre exhaust to replace the standard catalyst.
The sports cat exhaust option will enable you to pass a UK MOT emissions test or police road side checks.
All relevant fittings and gaskets are supplied
EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
