I have been running the Supermeggs 2:1 on my 06 Ultra and have been very happy with them. With my updated fuel map, I lost 2 or 3 mpg but that would be a question for my tuner folks.
Lately, I have been trying to trace down a rattle that gets worse when the bike is warmed up and in doing so, I noticed that there is no clamp attaching the lower pipe to the bracket by the transmission cover. My exhaust is supported by the flanges at the exhaust ports and the bolts at the muffler mounting bracket.
Did I miss something?
