Turbo whisling

[Streachy]

I had the used one that I purchased on e bay and being Sunday afternoon, no parts store open, I put it on to run the next 3 days. Now I have a whistle sound when boosting that gets louder with boost pressure. I believe it to be an exhaust leak where the turbo mounts since I had to reuse the gasket. Is this a possibility? Runs fine, better than with the old turbo, and I checked all the CAC hoses. No codes now. So will an exhaust leak at the turbo, the egr, or the exhaust pipe behind the turbo cause this whistling noise?

As well, when the engine is cold, start the engine and take a bottle of soapy water and spray around all the gaskets and you'll find it
