I have a akrapovic slip on on my 07 1200 and the difference was substantial. It may be your older electronics can't adjust for the pipe and you need a power commander to tune things manually for the pipe?
It was on with the Leo Vince pipe for about 8 months, maybe more. Frankly, I never felt my bike did well with the Leo Vince pipe. I've only done a few miles with the stock exhaust back on, we'll see how it goes over the next couple of weeks.
