How does a 2 stroke silencer work?

But back to riding without a baffle. The worst you can do is free up some air movement - which is good, unless it changes your AFR too much. It will change air fuel mixture and that needs to be corrected but you could run straight pipes and it won't hurt anything as long as it's tuned.
