Wastegate?

Im sorry, the reason I think its the wastegate stuck open is I couldnt FEEL an exhaust leak, but I could hear a steady hiss coming from that area. This leads me to believe that the wastegate is dumping into the O2 housing a bypassing the turbine, making no boost. Does that sound correct?

Edit - Wait, so it must be an exhaust leak, youre right. Otherwise, even if the wastegate is dumping into the exhaust system, the car should die when I block off the exhaust, unless there is a large leak somewhere. I think it could be the turbo to manifold gasket. I hope the turbo isnt screwed. I'll diagnose the problem further. Thanks for the input.
