replaced y pipe rushing air noise now any ideas?

i replaced my cracked y pipe yesterday and when i fired it up there is air leaking out somewhere up by the turbo. I put a powermax on a few months ago and it all lined right up but now with the new up pipe it seems to be off a tiny bit with the turbo but the clamp goes on fine and it seems to be boosting fine. i bought a new clamp for the up pipe to the turbo but i didn't get one for my down pipe. a mechanic at my dealer told me that those clamps don't really go bad i don't need a new one until it breaks, but it has been off and on probably 10 times in its life.

The most likely spot is at the y-pipe to turbo connection.

Put your hands back there on a cold start up....you'll feel the air leak. You don't have a lot of time before it gets too hot. The suggested order of tightening the connections are marman clamp first then the manifold to pipe connection. The marman clamp supposedly will not pull the pipe to the turbo inlet for the perfect seal, it must be mated BEFORE the clamp is tightened.

I'll be replacing the y pipe this weekend...I could feel the air coming out of the top flex part. I did an EGR delete recently and have had that damn whistle ever since...

i did my egr delete last year and my y pipe cracked about a week ago. the new pipe is already in the truck. so your saying i should loosen the pipe at the manifold then tighten it down to the turbo then re tighten the pipe to manifold back down?

Yes, that's the order I was told by a senior master tech.
