Don't have a sound clip, sorry, but it sounds so much better than a chav valve!
If you're ever down south enough from Aylesbury (i.e. Hemel/Watford area) you can listen to mine

What turbo you running then jay? Sounds nice. Am running a VF48 at 1.35 bar so doubt it would sound as good as yours.
What drawbacks are there to running the delete? More lag, shorter turbo life? Will I need a map tweak?
Cheers fellas. Very helpful stuff.

Mine sounds a bit like this, but much louder http://www.youtube.com/watch?v=OuNTnA5A2Fo
Drawbacks? None. Most turbos can take it, some can't...

Stick with your favourite exhaust + sports cat and you're as quiet as you want to be. If people tell you that you'll make loads of power from a decat over a sports-cat they're lying. Last year I was running around 500bhp with a sports-cat and easily passing an MOT etc - the power drop was minimal.

Might sound like a stupid question but how exactly do you do this? just plug everything up? the hole in the intercooler and the 2 hoses?
If so whats best to use? I can use the bung I got with my crappy Bailey dv for one hose but that just leaves the smaller hose and the hole in the intercooler. What do people use to bung these up? I've had a couple of ideas but some tips would be appreciated :-)
Sorry for the hi-jack btw but i'm sure there are others that would like to know the same

Lol. No worries. That's all I was going to do. Leave the recerc hose plug in, plug the small vac hose and make a plate for the intercooler. Sorted.
Already running a full cobra 2.5" exhaust with 200 cel mot friendly sports cat downpipe. Don't plan on full decat. Too much hastle. Made 334bhp and 381lb/ft with that. Happy with that level on wrx box and std clutch. Lol.

Unplug the ruin hose from the dump valve and put something in the small rubber pipe to block it off. Basically this is the vacuum hose that controls the dump valve. If unplugged from the dump valve then the dump valve will not work. It will effectively stay shut under pressure like a blanking plate. Simple test as rob suggested.
Good luck.
Good luck.

Is that the thinner pipe on the right of the standard re-circ? Would this be safe to drive like that with everything else as is and just the thin hose blanked off?

By no means do I advocate you doing this for anything more than a test without speaking to your mapper, also depending what Turbo you are running you may run the risk of damaging the compressor.
So to clarify, unplug the small vac pipe that is fed off the dumpvalve, plug the pipe with say a small threaded bolt, dont worry about plugging the DV nipple.
As said this will prevent the DV from operating thus causing back pressure through the turbo, and the shudder noise is the air escaping back through the turbo (the wrong way) as the turbo is charged, which is why I said you may run the risk of damaging the turbo.
