Who purchased one of my manifolds and has a tuned pipe that will fit to it?

I have a buyer that purchased my manifold and thought that I did the tune pipe that he saw with it?

I'm hoping that the person who bought my manifold see this posting and posts a reply back?

Robert Dunn is looking for the guy with the tuned pipe for information and details of the pipe so that he might be able to make one for himself?

Thanks for looking.

I have data for .8 to 1cc tuned pipes.

The Profi is 9" long can scale it from there.

A TD .020 pipe would be fun, ask him if he can do a .35cc pipe if able est. 5.5" long.

Sorry friends I was too busy with the boat and my car that I missed a certain conversation I received a message from Robert it doesn't matter it's not me who bought the parts But I have several models of my design but more focused on exhaust control to use them on radio controlled models Also all models available from cox manufacturing And of course some iteration of the original COX design But with my personal touch Here are some examples that I leave here
