Depends how loud you want it? Silly loud or noticeable?

These engines don't have a dump valve, only a recirc valve. The OEM one is a diaphragm, but the Forge 008 is a piston. You get a nice hiss out of it
You can use OEM one, or forge one, but you wont hear much noise unless you are remaped so you can dump more boost (1,4 bar instead of 0,7 for example), and unless you have short air intake (cone filter instead of standard airbox)
These engines use recirculating dump valves, so you can only hear woosh thru your cone filter..
There is also an option with Forge split r, wich dumps some air to atmosphere, but ive heard that it is not the best option for there engines.
It is also a good idea to remove n249 and connect DV directly to intake manifold, makes even louder woosh

If you fit a full atmospheric dump valve then your going to have a world of issues with the running of the engine. They need a certain amount to be recirculated, which is why they have a full recirc from factory.
You can fit a Forge Split R valve and have it on part atmospheric dump, although there are mixed results with these too...
I have a stock DV with stock airbox, a K&N panel filter with some holes drilled into the airbox, you can hear mine dump back through the system with no ill effects.

Yes I would stick with a recirculating valve as it is best for the engine unless your going for a monster build with standalone ECU etc...
I'd stick the new valve on and see how it runs, then you could smooth out the airbox, and add some holes for added effect.
I find mine runs really well and boosts nicely.
