Default exhaust valve

Hi there! I have a stock 2008 Train.

I am not clear as to a circular valve located just ahead of the muffler on the pipe connected to the rear cylinder. I notice that it opens and then closes when I blip the throttle at idle.

I read on an English forum that it was not on State side bikes, and being in Taiwan, I would like to find out a little about what it is and if I need to remove it when I install my new 2 into 1 Rineharts, Big Sucker and Thundermax next month.

If anybody has any info on what this doohicky is and what to do about it, it'd be appreciated.

Trev

Exhaust actuator valve, not exactly clear on their purpose though, I'm sure they are a emission device because they're used on HDI models and some California models.
