Your car will have the standard one that bolts to the intercooler Craig... some of the aftermarket ones bolt straight to the intercooler, the same as standard. But others have a plate (shaped like the base of the stock dump valve) with a pipe running out of the centre leading to a piece of pipework which allows you to fit a dumpvalve in the 'normal' way.

Next time I see you I'll take a look if you like.
