[The Atomic Ass]

I've started a new job recently that has me doing a very large amount of traveling. It pays well enough that even driving the 25mpg pig that is my 1996 Buick LeSabre is well worth it, but I would like to get back to two wheels.

Problem being that I do deliveries, and while space is not much of an issue, noise is, as sometimes my routes are long enough that I'm working past daylight, and discretion comes into play. So I'm curious to know if anyone is aware of an unusually quiet model, or, alternatively, an aftermarket exhaust manufacturer that is focused on silence rather than boisterousness.

Unfortunately, electric is strictly out of the question, unless someone makes an electric anything that can go 300 miles on a single charge.

ETA: I also have a dislike for CVT's, so I'd prefer to avoid those.
