How Mufflers Work (Technical Overview)

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

In a reverse flow muffler, exhaust gases are redirected through internal chambers, which helps cancel sound waves and significantly reduce noise.

• Reverse Flow Mufflers: Quietest option, ideal for OEM-style sound
• Straight-Through Mufflers: Higher flow with louder exhaust note
• Resonators: Reduce drone and refine sound

The Berklee BM0480 is designed for quiet operation, making it ideal for daily drivers or vehicles requiring reduced exhaust noise.
