Thanks guys. Byron I knew youd be all over that! You win a gold star sticker on your workbook.

I know theyre another bit of pollution crap but as i will be eventually selling the car, :-( I want to keep it factory so Ill put it back on, but probably wont connect it up as thatll probably be a pain in the arse... Then whoever buys it is welcome to turf it and put extractors on....
