Default Re: Skeptics Review of SBP Tuned Pipe

I picked up some copper tubing at Home Depot to experiment with and found the length of the copper tube had little effect on the power band. Doubling the length and eliminating it completely made no big difference in acceleration or top speed. My theory is you would have to make significant changes in length of the header pipe to do anything. The copper tube does not play a big part in this.

I realize this goes against everything Pablo and Ghost say here and on their site but it is what I experienced with my Zoom 80cc slant.
