Recently purchased 07 Road Glide 103, 255 cams 3" IDS with stock header. Set up is 9 each side open end caps. Left open end cap hole is about 1 3/4
and right is normal ( little over an inch). Looks like someone stretched out the left for some reason. I'm sure not a good idea. Anyway sounds good but as far as performance I think there may be more left on the table. Bike has a tuner on it but wanted to get disc count recomendation open and/or closed before any tuning. What do you think? Thanks in advance!
