It's a nightmare! I freaking hate it. Cold start is the worst with a catless DP.

What year is your car? If it's pre-2013 it should have a PWG, in which case the only way to fix it is to tighten the wastegate actuator. I haven't found anyone that will do it yet, as you can easily blow the turbo if you make it too tight. I need mine fixed badly.

My car is 2010 just got it last week!

Is it bad for the car or is it just a annoying sound that i can let it be?

You can let it be, it's more annoying than anything. BMW says its "normal" and just about everyone has it.
