How Mufflers Work (Technical Overview)

An exhaust muffler controls sound, flow, and backpressure by managing exhaust gas movement.

In a chambered and baffled muffler, exhaust gases are redirected through internal passages and baffles, which help reduce sound levels and smooth exhaust pulses.

• Chambered/Baffled Mufflers: Reduce noise while maintaining good flow
• Straight-Through Mufflers: Louder with maximum airflow
• Reverse Flow Mufflers: Quietest but more restrictive

The Berklee BS0143 offers a balanced exhaust note, making it ideal for drivers who want performance without excessive noise.
