I do suggest that before your dealer works on the car tell them about the exhaust and if they are friendly about that. Good luck and welcome there is lots of good info here.

also w/o insulting is it mild knock at low rpms?
That's a pretty accurate description, yeah. I think I'll let it be for the time being. I plan on taking my car by the dealer in the next few months to get it looked over and talk to someone about a few small issues before the warranty expires. And no, it's definitely not an engine knock. To me it sounds like something loose behind the head unit or somewhere around the middle of the firewall. I can live with it; it's done that since day one.
