This BMW M440i performance exhaust is made in 3.5"/88.9mm pipework and fits from the turbo to the centre exhaust to replace the standard catalyst.
The de-cat exhaust version is sold for motorsport and off-road use only worldwide.
The sports catalyst version replaces a factory emissions device and is not EC homologated. This may not meet current emission laws for road use in your territory.
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.
