Choose from two exhaust tones at the Press of a Button.

With regulations worldwide becoming stricter and the general public expressing increased criticism, Vandemon developed a variable-valved slip-on muffler that eliminates the OEM catalytic converter and heavy steel mufflers. Apart from a significant weight saving, this exhaust is unique because the operator can choose from two exhaust tones, Quiet or Loud, at the press of a button on the handlebars. 

How Does It Work?  

The system consists of three mufflers which a purpose-made titanium valve, when closed, directs all exhaust through a larger central muffler, which then exits through the silenced LH muffler to give an exhaust tone as quiet as the OEM exhaust. When the valve is in the open position, the exhaust will exit via the path of least resistance, which is the third RH muffler, with no restriction to gas flow, making for a deep tone and maximum performance. A purpose-made electric motor drives the valve, insulated from heat, and is 100% weather-resistant.  

• When tuning the Stealth exhaust, the technician will customise the tune to the valve open (loud mode). The quiet mode should only be used in suburbia and city limits when the engine is operated at lower engine speeds, as peak power is restricted in stealth at higher engine RPM, resulting in excessive exhaust back pressure if the engine is raced. 

•  The sole purpose of this exhaust is for the rider to be able to quieten the exhaust so as not to cause a nuisance to the general public and not be noticed when required, as well as have the luxury of a louder and more powerful exhaust when out on the open roads.

Appearance:

The surface finish is natural brushed titanium, which won't stain, corrode, or need polishing. Titanium is very resistant to acid and salt and dissipates heat twice as fast as steel.

IMPORTANT! Vandemon Exhaust systems are designed for performance and modest sound improvements. We at Vandemon do not try to meet noise emission standards because the results would be no different from what your OEM exhaust can achieve. Check with your country's governing body regarding noise emission standards, rules, and regulations.
