My sons 07 Dyna ran ok stock with the Thunderheader and no other mods but when taken to the dealer they recomended a little more fuel. Makes sense that with more airflow youd need more fuel. I wouldnt risk running to lean.

Is there more airflow with the stock AC? Same size hole going in, isn't this why it is recommended to do AC and pipes at the same time so that you do actually get more airflow. Just asking...

Agree you don't wanna spend too long running lean. A PC or XiED will fix that.

Just changing pipes should just change the sound of your bike. Now just don't go changing to a high flow intake without tuning. It will yellow/blue your pipes pretty quick. (don't ask how I know that)

I had to go with a Race Tuner on my Dyna with a Stage 1 Air Cleaner and a ThunderHeader. I tried the download first and the bike ran way to hot.
