So, I talked to someone at Rush and he was very friendly and helpful. I explained my situation and he said that the 2.5 inch is a pretty aggressive baffle. He said the 2 inch will tone it down a lot and bring it closer to stock. So, I went ahead and ordered the baffle from the distributor that sold me the pipes. Hoping to have them by Monday at the latest. On a side note, I explained to him that I made the transition from riding V-twins for the past 12 years to the flat 6 and he was super complimentary of the F6 and how "plush" of a ride it is.
