Yep, played around with the spreadsheet, you are correct John. It is just a coincidence that the blue line shows up at half the piston diameter.. when I change that value it doesn't go away.
I will update the video with that info

I will probably try to build a silencer. I have these desiccant tubes off a giant compressor that are the right shape.

Another great vid showing the labor intensive methods used to build a single expansion chamber!I used to tack up the whole pipe for proper fit till Wobbly at KiwiBiker commented that he works every joint with an internal ball mandrel and hammer,from each end of the pipe to get a perfect fit,leaving only the final belly seam for the last weld..That way all the seams are hammered smooth and round for each weld,smart man!!I copied his method and it does work well,takes longer,but building a pipe already uses waay too many hours..Thanks for taking the time making these vids to show others the way!!  |

If only others watching really knew how long a single pipe takes to build. I can’t wait to see how it runs (sounds)!

Yep. I use those mandrels to make the inside truly seamless (or a close proximity  ) I welded each section individually as well, and if I had not made the cardboard template exhaust I would have definitely tacked it, then broke it apart for final weld. |

Here is another great video that shows some pipe building. It doesn't show much but gives some simple tricks to get good fits and what another guy does.

Having access to stamped headpipe sections like Bill's does would sure speed up a pipe build!!

Sound clip of the exhaust. Had a bad coil so it wouldn't rev out, swapped on a malossi and it sounds great.
Also starts bogging because I only have the fuel line for fuel.
