Re: Exhaust MUCH quieter than it was
yeah, definitely wasnt just used to the sound. it was 100% quieter and nothing was wrong with the pipe. so i did some messing around with the SET valve cables down by the headers...loosened the nuts and adjusted them. what had happend is some how the SET valve got adjusted so after the valve went through its cycle it remained like 90% closed which restricted the air flow to much. little adjusting of the cables and now the pipe is back to being loud as hell like it was. put 100 miles on the bike and didnt have to remove the SET valve, but after hearing the difference the adjustment made and feeling the difference in throttle responce im 100% removing that valve as soon as i get a chance.
