So why does no one sell a matched carb/exhaust setup?

[Dryheatbob]

A basic(really basic) rule I’ve always applied to engines is the faster it moves air/fuel through it the more power it can develop. Yup. Basic. One of the easiest ways to gain power on these little motors of ours is to replace the carb and exhaust with ones that will do the above more efficiently.

So why no “kits”? And why are most articles and YouTube video comparison tests on one or the other but never both together? Seems a natural thing to do given most swap both or are advised to do so.

Because most people who get into motorized bikes with the CGs are super cheap, at least when they get into it. A Kit has to be cheap.
