    so, I have a modified pocketbike pipe. I had a pretty short header, and decided to lengthen the header for a wider powerband. I extended the header the entire length of the bike, and see no difference in performance, except that top end is a little smoother. I was hoping for more bottom end, i.e. hill climbing, but am not seeing it. what am I missing?
