Exhaust

Long answer: Because it’s not made for it. It’d probably make less power.

A exhaust chamber has what’s called a “tuned length “. There are many factors in determining that. Now which order that will make the most sense :rolleyes:

Tuned length is determined by desired peak RPM. That would actually be almost the same for any engine. However the size/volume would be totally wrong. That starts at the port area at the cylinder. Which the CR would have more than 2X the area at the port exit.
