What is Torque expansion chamber?

A torque expansion chamber is a type of exhaust tuning device commonly used in two-stroke engines to enhance performance. It works by using the principles of wave dynamics to create back pressure and enhance the scavenging of exhaust gases, which can improve power output and efficiency. By strategically shaping the chamber and its dimensions, it can optimize the engine's torque curve across various RPM ranges. This technology is often employed in motorcycles, go-karts, and other small-engine applications to achieve better throttle response and acceleration.
