Default Re: Well I just had to say this and see if anyone else has experienced this

If the expansion chamber isn't making more power than the stock exhaust then something is not tuned correctly, IOW you aren't getting the full power on the pipe. Could be your mixture, but if you have specifically jetted the bike for the expansion chamber, then it's pipe tuning. You should definitely feel the bike come on the pipe, if not adjust the overall length from exhaust port to chamber.
