Bad noise from exhaust side, bad turbo???

[jet]

Hi everyone, I am in a bit of a dilemma.

I have an JDM S15 SR20DET and it is making a very strange noise, it could be a bad turbo, exhaust leak...

I have done some research and some people fixed it by changing the gaskets? some said re-tightening the exhaust manifold and turbo, others have said they replaced their turbo.

If anyone has experienced or heard something like this. What could this be?

This morning I checked for boost leaks just in-case, I did find one, and I have resolved it, however that was not the issue.

What can you guys make out of this. Here is the video of noise in question:

I hope you guys can help out...

Turbo to manifold gasket is loose to that means the turbo studs/nuts have loosened/snapped. Common problem of you have stainless exhaust because of the extra weight

Thank you!

You can see the manifold to turbo gasket blowing in the vid. Easy enough to fix, good time to fit braided turbo oil and water feeds too.

Hey guys, today was the day we fixed the issue. The Turbo gasket was completely finished, broke in half.

We replaced the exhaust gasket and the turbo gasket and everything is all good.

No odd sounds like the one in the video.

Thank you guys for the help! MUCH APPRECIATED!
