Search wooshy wooshy and it explains all.
Basically if you want a loud dump noise you could possibly do the following.
1.install a forge 007p DV
2. remove airbox and smooth all the interior ridges out.
3.install a green cotton panel filter
4. remove offside wheel arch liner
5. remove the incey wincey air intake pipe from the arch.
6. install a new air intake (or just leave the box open and the arch liner out)
If you do this, you'll get this noise.....

Alternatively you could install a Ram air filter which will give a louder noise too as the DVs noise will sound better through a cone.
Open filters which use oil to lube and stuff, tend to kill the MAF too.
Believe me mate, you'll want to research this mod before you go ahead and think you know what you're doing.
it'll pay in the long run
