HELP!!!!!!!!

Howdy all!
After a mammoth task of changing the up-pipe on my 2001 WRX(bugeye), noticed a strange exhaust noise from the aforementioned area!
Basically, it sounds as if its leaking, however no leaks seem to be there(if that makes sense!)
We changed the up-pipe gaskets, but we think it may be the gaskets on the r/h manifold? We just used the old gaskets when putting back on and some gasket paper (or whatever you call it!)
However, im led to believe the noises may be the internal gasses(?), as the up -pipe has no cat conv. (its a stainless steel one from Subaru 4 you)
Can somebody PLEASE shed some light on the matter as i really dont fancy spending another 9 hours smashing the granny out of my hands doing it all again!!
My engine bay looks like ive sliced somebody up under there!

Re: HELP!!!!!!!!

What ever part of exhaust you getting noise regarding it blowing, start the engine and then use a small bit of paper and hold this over the gaskets where ever you think is blowing and if the paper moves and flutters thats where it blowing from. Simple test and accurate
