If you have an 06 AIS kit the plug for the exhaust port wont fit. You will have to fabricate a plate or wait for an 07 kit.
i had a 06/07 kit and the plug didn't fit, I need a piece of metal like this. For a quick fix, I left the tube on and put the aluminum cap over it, using a bit of the hose inside to seal it. that soft metal insert would not have fit.
This looks much better, will have to get on that
