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 disrupting and smoothing these pulses using internal chambers, perforated tubes, and baffles.

• Chambered / Baffled Mufflers: Use internal baffles to reduce noise and smooth exhaust pulses
• Straight-Through (Free Flow): Maximise flow with a louder, sportier sound
• Hybrid Designs: Combine flow efficiency with improved sound control

The Berklee BS0236 uses a free-flow design with centre baffle, offering a balance between performance and noise control, making it suitable for dual exhaust and higher-flow applications.
