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, baffles, and sound-absorbing materials.

• Reverse Flow Mufflers: Redirect exhaust gases through chambers to significantly reduce noise and drone
• Straight-Through Mufflers: Maximise flow with a louder, sportier exhaust note
• Hybrid Designs: Balance performance and sound control

The Berklee BS0932 uses a reverse flow design, making it ideal for drivers wanting a quieter exhaust system while maintaining reliable performance.
