When I had the factory downpipes and exhaust I heard nothing , when I had factory downpipes with Full Meistershaft exhaust I started to hear the rattle it wasn’t too noticeable unless I was next to something and slightly revving it I heard the rattle , when I went catless is when it got very noticeable especially right before stopping , but only with the windows down windows up I hear no rattle .
I have cold start delete so on the first start I can hear the wastegate rattle but when I hit sport+ button it disappears,I guess the wastegates tighten up and move closer to the turbo housing that lessen the rattle .
Btw the rattle doesn’t bother me because I know it’s normal for this car but it would be nice if there was none, I wouldn’t change it for anything because that glorious sound of the turbos is so intoxicating
