Emissions and road use

- These should pass an MOT emissions test when fitted
If your later model car has OPF or PPF filters they will need coding out, so you will need to use a tuning company that can carry this out.
Installation
Professional installation is recommended, as exhaust tolerances can vary and space can be tight. Feedback on this product has been that it is very easy to fit.
