Yep... Blue spring with both shims at the bottom/piston-side. Sounds damn awesome, yet still very stealth. The guys where I had it installed ran it w/out the recirc and said I should do that, plug the recirc hose to keep the CEL from hitting - teeeemmmmmpppppting
Got the AEM CAI also installed and the turbo spooling sounds like a BEAST (cool)
I'll have pics up soon...
Nope... even when plugging the recirc hose, the car can't idle for carp

The 'whooooosh' and whistle are loud enough because of the CAI that my fuel economy is crap - I keep getting on/off throttle just to hear it
