Can you comment on your level satisfaction? If you're looking for a subtle loudness increase over stock, but want the upgrade to be worth it in terms of sound quality, which one would you recommend?

Which one is louder on the cold start too? The cold start on this car is already so loud, so trying to find the one that doesn't increase it as much.

Looking for getting something basically like the akrapovic without spending that much money.

Thanks!
