Applications

• BMW S1000R (2021–2024)
• BMW S1000RR (2021–2024)
• BMW M1000R (2021–2024)

Unmatched Innovation in Stealth Performance

In response to stricter global noise regulations and growing public demand for quieter performance exhausts, Vandemon introduces the BMW S1000RR to our renowned Stealth Exhaust lineup.

Vandemon has pioneered a unique Bimodal Exhaust System, offering riders the flexibility to toggle between QUIET and POWER modes with the press of a button.

Bimodal Functionality
This cutting-edge exhaust system features a lightweight titanium bimodal muffler replacing the catalytic converter. In QUIET mode, a titanium valve redirects exhaust gases to a stealth muffler, producing a subdued sound while maintaining performance. Press the button to engage POWER mode, and the exhaust gases bypass the stealth muffler, exiting directly through an unbaffled muffler for maximum sound and performance.

The system is driven by a purpose-built BMW electric servo and powered by a custom wiring harness that seamlessly integrates with the OEM BMW wiring loom under the seat. A conveniently mounted handlebar switch allows riders to switch between modes effortlessly.

By eliminating the heavy, restrictive OEM mufflers and catalytic converter, the Vandemon Stealth Exhaust reduces weight and significantly lowers stored and radiated heat. Titanium’s natural heat dissipation ensures quicker cooling for optimal performance.

Advanced Manufacturing
Vandemon utilizes a proprietary welding process to create ultrasonically perfect, flush-finished joints, ensuring superior durability and performance.

Why Choose Titanium?
Titanium is the material of choice for high-performance industries such as aerospace, motorsports, and marine applications due to its exceptional:

• Strength-to-weight ratio
• Corrosion resistance
• Heat dissipation capabilities (twice as fast as stainless steel)
• Resistance to high temperatures without distortion or oxidation

Advantages of Titanium Exhausts

• Ultra-lightweight for enhanced power-to-weight ratio
• Won’t corrode or change color from water exposure
• Requires no polishing, unlike stainless steel or aluminum
• Cool-to-touch design, dissipating heat faster
• High resistance to extreme temperatures
