Heard Kitaco exhaust is quietest. Can’t find one.

Looking everywhere for a Kitaco exhaust. Can’t seem to find one, even on WeBike. Anyone have any link they can send?

I’m trying to find the quietest exhaust (run stock now) that will let me get the most out of carb, jetting, intake, variator and CDI mods. If anyone knows something real quiet, let me know. Or if you have facts that back up leaving it stock (that’s the dream). I’m fine if it’s the difference of 1-2 mph. But if I’m losing 5 mph, I’d want an exhaust.

You’re the best.

Not quite a theory to back up the stock exhaust but they came in 2 variants. There's an A-1 and A-2 style. The A-1 has larger diameter piping coming off the header. My 07 has the A-1 style and the spare I bought off a 2015? (didn't know there was a difference) has the A-2 muffler. My theory is that the smaller diameter pipe slightly restricts top end power to give you more torque in the low end. I have nothing other than standard engine theory to back up that claim though. That being said I've hit 50MPH on a small downhill with my stock A-1 muffler. So yea, maybe live the stock dream?
