Mufflers are only used to deaden sound... don't think its used for much else.

For 4 strokes, I don't think they're called expansion chambers. But the exhaust system in a 4 stroke is designed for a slightly different purpose.

On 2 strokes, the pulse is used to push charge back in. On 4 strokes, the exhaust system should be designed in such a way that no pulse goes back to the cylinder. Also, if not designed properly, on a 4 stroke, you could fry your exhaust valve...

Tech whizzes, please correct me if i'm wrong.
