I’ve installed krona downpipe and brand new gaskets. It was making a noise before I installed the downpipe, turbo.

main concensus so far is that its not the turbo. I tried smoke test but couldnt find anything at low pressure (<5psi) however it only appears to happen on high(er) boost. At this point I am not prepared to run 10-12psi into my inlet or exhaust to test it for leaks that open at higher pressure as i am worried it will break something.

Idk how to post the video I have of it, but yeah. It’s definitely the same noise. It’s really irritating.

to post my video I just loaded it on youtube and linked it to the post.
On the plus side.I have had it for a few months and it doesnt seem to be getting worse or effecting anything adversely. I just worry that it might cause damage so drive around at about 70% throttle. love to know what it is though, so i can get on the loud pedal safely:D.
