Why is WRX turbo silent?
I drove my friend's WRX yesterday, and I couldn't hear the turbo spooling. Is there anything that can be done to the car that will make the turbo much louder? I love the HISSSS of the Evo, for example, when it starts spooling.

There are mods documented on here about removing the intake silencer. That is one way to hear the turbo spool, BOV, etc... Or, a short ram intake works too, but the jury seems to be out on that topic.
if you want sound, a bigger turbo would be suggested. the stocker is much smaller compared to the 16G on the Evolution. however, with a downpipe, and up-pipe you can hear the WRX turbo spool quite noticeably.

Like stated above, I removed my intake silencer and I can hear the turbo and BOV much better. It makes driving my REX that much more fun. I'll be interested to hear it once I get my Blitz short ram intake, if it ever gets here.

Its a TD04 not a T88 
And since its more prone to a whooosh sound than a whine (like the K03) its not as loud/perceptable. If you're used to a 1.8T's stock K03 you're probably listening for the wrong sound. Take out the resonator like everyone's saying and/or put in a short ram.

Don't bother removing the silencer...
In my opinion it's a waste of time. I took mine out expecting
to hear what everyone is talking about. Can't even tell
a difference.
If it doesn't even give a performance gain, then it really
is a worthless "mod".
I would venture to guess Subaru engineers know a good
deal more about the intake than we do. It's got to be there
for a reason.
I know I'll catch a lot of crap for this one.

I found my filter got much dirtier faster with the silencer removed than with it in. The inside wheel well gets very dirty from what I have seen....not the greatest place to suck air from.
