Thanks to Doug Levin, gbatejan, and 1fastviper - you guys nailed it! Fairly substantial crack/opening in my drivers side header that was most noticeable when cold starting, but really quieted down after warm up.
You know what you need? You need to upgrade to a real set of headers! Just got them ceramic coated to keep the temps down. Check these out:

I just installed Roe racing H/F cats with the stock mufflers on my 08.
The car is also much louder when cold starting and quiets down after warm-up. Could I have cracked a header when installing or is this normal ?

I have Randomn Tech Hi Flow Cats on my 2009 with stock manifolds and mufflers and it does the same thing on mine. Loud for about a minute then settles down. This is not a result of a crack in the manifold, instead it is the motor causing a different tone during cold start and the fact the cats aren't heated up yet. I have a BMW M6 and it does the same thing. Quiets down after about 1 minute.
