With noise emission regulations worldwide becoming more strict and increased criticism from the general public, Vandemon came up with Titanium Slip-On mufflers & link pipes that do away with the OEM heavy steel exhaust.

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 It also enhances HP and torque significantly without the need for a tune and even more so if tuning is sort as this exhaust will offer no limitations to what a tuner can arrive at.  

• How Does It work?  

  The system consists of two mufflers. A top quieter muffler receives all exhaust gas when the valve is closed, then when selected by a handlebar mount switch the valve at the entry to the lower straight-through unrestricted muffler opens and exhaust gas will take the path of least resistance via the lower muffler that has no restriction making for a very loud deep tone. For those that want to reduce the sound slightly a removable baffle is supplied. The electric motor that drives the exhaust valve is a purpose-made weatherproof servo made by BMW and comes with a wiring harness and switch that takes power from a 12-volt ignition live supply. 

   

• 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/ salt resistance and dissipates heat twice as fast as steel for less heat soak and retention.

Why buy a titanium exhaust? Due to its strength, weight, and anti-corrosion quality, Titanium is found in the most demanding applications on Aircraft airframes, jet engine compressor blades and ducting, deep-sea saltwater vessels, steam turbine blades, rocket motor cases, and F1 and MotoGP

Other advantages of Titanium:

• Very light, Increased power to weight ratio
• Won't corrode or discolour
• Never need polishing like stainless steel & aluminium
• Dissipate heat twice as fast as Stainless 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 end results would be no different from what your OEM exhaust can already achieve. Check with your country's governing body regarding noise emission standards rules and regulations.
