Triumph Speed Triple 1200RS & RR Bimodal Titanium Stealth Slip-On Muffler
Deletes the Catalytic Converter
Years - 2021-2024
Choose from two exhaust tones at the Press of a Button.
With regulations worldwide becoming more strict and increased criticism from the general public, Vandemon developed a variable Valved Slip-On muffler that does away with the heavy OEM catalytic converter and steel mufflers and uses the OEM Triumph headers. 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. LISTEN to the attached Sound clip, where at the 14-second mark, the exhaust switches from zero restriction to Stealth mode and back again.
How Does It Work?
The system consists of two mufflers and a purpose-made titanium valve that, when closed, directs all exhaust first through the baffled Pre-muffler, which looks like a catalytic converter (that is no longer used) seen under the motorcycle and then lastly exits through the larger straight-through unrestricted LH muffler to give an exhaust tone as quiet as the OEM mufflers. When the valve is switched to the open position via the handlebar-mounted switch, the exhaust will exit via the path of least resistance, which is the large LH muffler with no gas flow restriction, releasing that glorious Triumph triple sound.
The servo motor that drives the valve is a quality German-made BMW component that is weatherproof, heat-insulated, and very reliable.

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 the Stealth mode is restrictive and will create 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. The rider also has the luxury of a louder and more powerful exhaust when out on the open roads.
