Thunderheader 1069B Thundercone Slip-On Muffler, Black - 2012-2016 Dyna Switchback & 2014-2017 Dyna Low Rider
Heatshield
Experience a powerful combination of increased horsepower, torque, and the unmistakable Thunderheader sound with the Thundercone Slip-On Mufflers.
What sets the Thundercone slip-ons apart are their innovative design featuring a patented collector instead of a conventional baffle. The collector works by efficiently directing spent gases through four acoustical dampening chambers, optimizing the exhaust flow for maximum performance gains.
To further enhance the exhaust dynamics, the Thundercone mufflers incorporate a cutting-edge flow director. This multi-tasking component not only guides the outgoing flow through the acoustical dampening chambers, creating a spiral motion upon exiting to the atmosphere but also forms a pyramidal-shaped anti-reversion trap. By doing so, it minimizes the amount of air rushing into the system, allowing for optimal performance.
Working hand-in-hand with the flow director, an integrated diffuser shroud is built into the reverse cone. This patented feature diffuses the air rushing in when the pressure inside the system becomes equal to the atmosphere. This ensures smooth airflow and minimizes disruptions, leading to improved overall performance.
