OK ... 605's installed and this bike has come to life. The sound is awesome, throaty but not way loud. I haven't done the AI removal yet and there is a slight popping on decel. Really, not as bad as I thought it would be.

I have a real hard time paying close to $30 for 2 bolts and 2 copper washers and 2 plugs.
