Show off your muffler mods

A 2 cycle is a lot different than an engine with valves.

Indeed, but, even an engine with valves benefits from a well tuned exhaust. Cam profile affects that as well. Thats another rabbit hole.

Im enjoying the discussion yall.

A little grinding and some black paint and it will look pretty good

Exactly, that is why headers have collectors, and tubes of the right length and diameter.

Conversely, Funny Cars and Rails generally do not have collectors, but they still pay a lot of attention to the length and diameter of the tubes.

Similarly on the intake side, a dual port manifold will provide more low-end and midrange power, and a single plane will provide more high-end power.

This is what I meant by pipe, not an expansion chamber.

Not ugly at all.
