David M:

Concerning your previous post and I think that you would agree is that most people here that have had some exposure to expansion chamber systems, pipes and formulas go way beyond the simple thinking that you could put anyone's 3 Holer pipe from any other brand or type or modified version and that pipe from some simliar displacement engine would even begin to work if at all. Pipe formulas are based on precise engine specs that the manufacturer of builder would know or would provide as one relevant start point and from there it is test to fine tune the pipe. The ghist was that there is the technology out there that shows that a single expansion chamber matched to a 3 holer can work well and not be a great weight that could be constantly breaking and needing repair compared to some triple bunch of heavier or vibrating a pipe system that would.

That is all I was ever trying to get across.
