   have you had an MOT/service or something to say that you NEED to lower your CO2 emissions levels?? because if not i would leave it as it is as the best and only thing you can really do is whack a new catalyc converter on and that can cost you quite a few quid.

   Do all the above, then before the test take it for a good rag, gets the cat nice and hot should help you out with the emissions

    Bottle of injector/engine cleaner might help as well. I've had good results with BG44K injector/fuel system cleaner. It's ridiculously concentrated compared to something like redex or stp cleaner. Dump the can of BG into a full tank and then refill the tank once you get down to 1/2 or 1/3. Gives it a little more time to work.

    have a good drive before having it tested so it's done on a warm engine.

    If back box is blowing, get it fixed or replaced, that should sort your problems
