is it only on boost? maybe you have moved the up pipe and cracked the flexi.

check that the headers themselves have good weld scenes. the noise might be that it has better flow

You'll more than likely find one of the gaskets has blow by. If the leak is only small it causes a whistle rather than the usual burble blow sound because its acting like a reed and vibrating.
