Please help...

I was driving my car today, at WOT and shifted from 1st to 2nd gear. As soon as I let the clutch out to drive in 2nd and get back on WOT, I head a loud CRUNCH followed by a bang and what literally sounded like something falling from my car and being run over by a truck.

I thought, oh sh*ite, there goes my tranny. However, it wasn't. My car immediately sounded like a REALLY bad lawn mower or a helicopter.
My turbo still boosts, but not QUITE as well and it seems to take longer to boost and then comes off of boost REALLY fast. Also, my EGT sensor is now dead--or reads nothing.

The lawnmower sound gets louder the more I'm on throtle and is just a dull ricey noise when I'm cruising.

While my car used to have noise all over the place (i.e. from the turbo spooling, the CAI, the exhaust in back, etc) it now seems to all come from the front turbo-side of the engine.

I popped the hood and couldn't "see" anything wrong. I looked under the car and couldn't see anything wrong. I put my hand on the exhaust and still felt gas coming out. So, I have no clue what's wrong. Any comments or thoughts would be appreciated. This is my BAAAAABY and I'm on the verge of a break-down.

For the record, my relevant mods are:

AEM CAI
Perrin Lightened Crank Pulley
Perrin Uppipe
Perrin Catless Downpipe
GReddy Evo Exhaust
Walboro Fuel Pump
STi Injectors
APS TMIC
IHI VF-34 running 17.5 pounds o' boost
ECUTEK reflash

PLEASE HELP.
