Just got back from Sturgis. Talked to the Rinehart guys up there. I asked if the high flow baffles would make any difference? They had them on a CVO 110 engine, so we went and fired it up to take a listen. What a difference in sound. It sounded like it woke the motor up compared to the stock baffle. I couldn't get my bike on the lift fast enough. I also went with the new end caps they just came out with. They look awesome. The one thing I did notice when I got on the road was it seemed like the heat from my motor went down considerably. I was surprised. For you guys that still have the stock baffles in run to your shop and swap them out for the high flow. Also I asked if it would mess up my tune and they said the only thing it would do is maybe pick a few horses but leave the torque alone. The other thing I noticed that it seemed to help my throttle response. Anyway I am very happy with my decision. End caps are a little pricey though. $260. They don't even have pics of the end caps on their website yet. I will try to post some pics. There are 4 different choices of end caps.
