This is a very thought provoking thread, and address one of the core issues I have with the '09 FLTRSE3. Engine heat! Here is my setup: Stock, ceramic coated, cat-less '09 head pipe, Fullsak 1.75" cores, dyno tuned for the midrange power curve, & thigh protection. I live in So. NV and was riding yesterday in 85 degree + heat for the first time this season, and the bike was very warm to ride, and I have six more months of high heat in my future that I would like to better manage when on the bike if possible.
If I am understanding you all correctly, by going with the V & H Power duals, a re-tune, many have experienced a dramtic heat reduction, and a nice performance bump in the midrange. Was there any impact on your mileage by going with the V & H set up? Also, need to understand from those who might be running the Fullsac X pipe their experience relative to heat reduction and overall performance. Not excited about reworking the exhaust system again, but will seriously consider if these possible changes produce a favorable outcome.
