Why do two-strokes sound different?
Two-stroke engines do not have intake and exhaust valves to regulate the flow of fresh air into, and exhaust gas out of the combustion chamber.

Why is my 2 stroke so loud?
The main reason that two stroke engines are loud is that they fire twice as often as four stroke engines. Two stroke engines have a very extensively designed exhaust system (expansion chamber) that reflects the sound wave back to the cylinder at a specific time.
