With regulations worldwide becoming more strict and increased criticism from the general public Vandemon came up with a variable Valved Slip-On muffler which does away with the OEM catalytic converter and heavy steel mufflers. Apart from a significant weight saving, this exhaust is unique in that 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. A purpose-made titanium valve that, when closed, directs all exhaust through a larger central muffler which then exits through the smaller LH muffler to give an exhaust tone as quiet as the OEM mufflers. 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. The electric motor that drives the valve is 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 when in suburbia and city limits when the engine is operated at lower engine speeds as the Stealth mode is restrictive to any power increase and will create excessive exhaust back pressure if you race the engine.

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 as titanium has a very high acid and salt resistance and dissipates heat twice as fast as steel.
