Blaster triple exhaust port questions

Not bad!
I do believe you are looking for an exhaust port and triple shape like this:

It can be done with a Dremel and some files.
The point is to get a strong exhaust signal up the pipe as the piston uncovers the ports.

I understand this drawing now lol. Thanks for the shape outline.
