Im kind of in the same situation with mod's so far ive done:

k&n air filter
full magnex system
custom de-cat
bluefin
denso iridium spark plugs
magnecore ignition leads

looking into getting a 4-2-1 manifold but i want to get close to 200bhp as possible so i dont want to buy anything else that is going to be redundant whilst trying to reach this figure,

can anyone point me in the right direction or if its possible?

sorry for hijacking your thread. . just thought it would be relivent
