How Mufflers Work (Technical Overview)

An exhaust muffler controls sound, flow, and backpressure by managing how exhaust gases exit the engine.

As exhaust gases leave the engine, they travel as high-pressure pulses. A muffler reduces noise by redirecting and smoothing these pulses using internal chambers and baffles.

• Chambered Mufflers: Use internal chambers to reduce noise and control exhaust tone
• Straight-Through Mufflers: Maximise flow with a louder exhaust note
• Hybrid Designs: Balance sound control and performance

The Berklee BS0818 uses a chambered design, making it ideal for applications where controlled noise levels and smooth exhaust tone are required.
