Does anyone make a tuned pipe for a saito 100 the only thing i can find are pitts style muffler thanks steve

You could get a turbo muffler if you wanted. What is the reason? Space, or power? If it's power just step up to the 125 and you'll be set.

A tuned pipe? or an after market pipe for the saito? I dont see how a tuned pipe would work on a 4 stroke but here is a link to some.

Since you asked in the 3D forum, as others have stated, I don't think you really should want a "tuned pipe" for a 4 stroke.

The pattern guys use these kinds of pipes to make the motor quieter. They don't add any power and aren't lighter than a stock muffler which is pretty small to begin with.
