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.

i noticed the hose from my tmic to my turbo has a very tight bend in it. would that cause anything? its litterly half the hose is blocked by the bend

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.

I miss my TD04 just because of how whistly it was through the exhaust. I loved it so much
