Kawasaki H2 H2R Vandemon Bimodal Stealth Titanium Exhaust System

VANDEMON The #1 choice by H2 owners & professionals all over the world

Years 2015-2024

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

With noise regulations worldwide becoming more strict, Vandemon came up with a unique Bimodal valve muffler that, at the press of a button, you can choose from OEM quiet or straight-through unrestricted power with a standout sound to match. This purpose-made full exhaust system is made from polished Ti1 Titanium with a very bespoke & unique muffler that has two separate chambers which is the same as having two exhaust systems in one. How Does It Work? With a Titanium butterfly valve mounted before the muffler, the exhaust gas is redirected via a more conventionally baffled section of the muffler that reduces noise to OEM DB levels. when the valve is in the open position exhaust gas will then choose the path of least resistance and exit via the straight-through un-baffled section of the muffler.

The OEM catalytic converter and heavy steel muffler & headers are also eliminated making for a much lighter exhaust system that is 50% lighter than the OEM Kawasaki exhaust due to the use of lightweight titanium used that is polished to a high luster and will retain its appearance without the need for polishing. 

• 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 above 6000rpm. 

   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.

Tuning
There is no requirement to tune the engine to suit, but for best results, we recommended Re-Mapping.  Additionally, the power valve and catalytic converter are eliminated to accommodate this system, so please check with your country's laws & regulations regarding the removal of these systems before choosing this product.

Our exhausts are professionally packaged to prevent damage in transit and arrive in a natural brushed finish that transforms to an iridescent blue, purple & gold colour beginning at the engine headers after only one heat cycle.

WHY BUY A TITANIUM EXHAUST?

Due to its strength, weight and 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, etc. F1 and MotoGP.

OTHER ADVANTAGES OF TITANIUM:

Very light, Increased power too weight ratio
Won't corrode or change colour from exposure to water
Never need polishing like stainless steel & aluminium
Dissipates heat twice as fast as stainless steel
Won't distort or oxidise at high temperatures

 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 already achieve. Check with your country's governing body regarding noise emission standards rules and regulations.
