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 while allowing efficient flow using perforated cores and sound-absorbing materials.

• Straight-Through (Free Flow): Maximises airflow with a deeper, sportier exhaust note
• Chambered Mufflers: Reduce noise and smooth exhaust pulses
• Hybrid Designs: Balance performance and sound control

The Berklee BS0812 features a free-flow design, making it ideal for applications prioritising performance and minimal exhaust restriction.
