THUNDERHEADER Black Thundercone Slip-On Mufflers – 1066B

Thunderheader Black Thundercone Slip-On Mufflers – 1066B

Increased horsepower, torque and unmistakable Thunderheader sound

A patented collector is used instead of a conventional baffle in the muffler

The Collector is designed to direct spent gases through four acoustical dampening chambers

The flow director serves a multi-task function: directs outgoing flow through four acoustical dampening chambers creating a spiral motion upon exiting to atmosphere and it also forms a pyramidal shaped anti-reversion trap to minimize the amount of air rushing in

In conjunction with the flow director, a diffuser shroud is built into the reverse cone, this patented device is designed to diffuse the air rushing in as the pressure inside of the system becomes equal to atmosphere

There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (bluing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the CHEMS/LUBES section for products that will help prevent or remove bluing.

 

Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during, or after, installing their product. If a jet kit or fuel processor is recommended, see the FUEL/INTAKE section
