Still probably has a bent/chipped fin. As long as its not smoking and is holding boost, it should be fine!

For a reference, this is what my old K04 sounded like in my A4.

Maybe your turbo is working harder (spinning faster) to maintain pressure past that bend. I would definitely try to fix that, your performance should improve a little bit.

Mine is loud like that too. But it is in top notch condition. I figured it would be quieter like a wrx. I contribute mine being load to 3" intake and 3" exhaust

Mine was barely louder than my VF-11. Definitely wouldn't say crazy loud. But its pretty subjective too.

Mine is a lot louder than the vf11 as well. I had concern but have been driving it for a while with no ill effects and great boost.
