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 lights may activate after removing the standard O E catalyst. An ECU remap is recommended to correct this and to stabilise any power increases.
