Important notes
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.
EML check engine lights may activate after removing the standard O/E catalyst. An ECU remap is recommended to correct this and to stabilise any power increases.
Cobra Sport accepts no responsibility for the use of parts which remove emissions devices on the public highway. It is the customer’s responsibility to ensure all local laws are adhered to within their home state or country.
