when running high boost (10-14 psi) between 4500-6500 rpm. The noise seems to be coming from the exhuast side of the engine. The car still pulls fine, everything seems normal except the loud noise that sounds like a car horn. I have recently replaced ALL of the exhaust gaskets and the noise is still there...although it sounds different since I installed the Greddy Turbo extension.

Anybody got any ideas? Is this normal? I haven't really driven any other turbocharged cars to compare. I have a crappy video that you can hear the noise in but I haven't found a place to host it yet. Thanks guys!
