    Fresh oil change, valve clearances, don’t dress your tyres. Make sure the tyres are in good nik. Clean/change air filter if it needs it.

    Edit: check plugs, replace if necessary.

    Sweet got my service coming up soon so will get all done. Also I got a 2.5" catback system, is it worth upgrading to a 3inch system or is 2.5inch good enough.

    Yeah get a service and check car over like tyres etc before hand,
    Seems your not changing the header I would just stick with a 2.5". I'm not sure a 3" catback would be worth it without a header.

    Sweet. Also I came buy the Japspeed 4-2 Header on H-Tune website which says blots direct onto existing cat. Is there any point in this header or best to leave the OEM one.

    Personally I would'nt bother just stick with OEM.

    A JDM one off an EP3 or DC5 are worth looking at if you can get your hands on one of them. They are a much better design than our versions and the cats are slightly freer flowing but still pass the mot.
    They are like the Spoon versions.

    For the most gain you will need a 421 header, secondly a JDM one, otherwise just stay as you are.

    Cool. What about the sports car are they worth the money?

    They'll need a lambda-fooler/extension or k100, and they generally need to be damn hot to pass. Freer flowing though, sure. :/
