Any other rattles near the exhaust are usually wastegate rattle. It is normal in the sense that it is a common problem on these cars. Bring it to the dealer if you are under warranty and stock.

Any other excessive ticking noises may be valve train noise. Go to dealer if it is a concern but they will likely do nothing unless its excessively loud or throwing codes.

The e36 and e46 problem were notorious for needing valve timing adjustments as early as 20,000 miles, but the N54 doesn't have that problem.
thanks jeff, the more i talk to people im leaning towards #2 you listed, but why would this start now and notoccur in the first 5 years ive had the car?

i will say the car has never been in weather that is this cold before if that makes a difference, i store it but drive it around my parking garage once a week.
