So I read on here (I think) that someone cut the inner tube that goes from the bottom up to the top portion of the stock muffler (the stinger) and cut it in half or something. So I did the same thing. I cut it down to 1/4 and put it back together and wham!!!, increase in throttle response and speed. Did I just turn the stock muffler into an expansion chamber? What is going on here?
