Vandemon Performance Bimodal Stealth Titanium Slip-On Mufflers
Experience a remarkable +54% more torque at 2500 RPM after tuning with Vandemon's innovative bimodal valved slip-on muffler. Designed in response to increasingly stringent global regulations, this exhaust system effectively replaces the OEM catalytic converter and heavy mufflers. With a simple push of a button on your handlebars, switch between two distinct exhaust tones: Quiet or Loud. Enjoy not only improved performance but also significant weight savings.
HOW IT WORKS
The Vandemon exhaust system is engineered with three mufflers and a specialized titanium valve. In Quiet mode, the valve remains closed, directing exhaust gases through the baffled central muffler and exiting via the left-hand muffler, providing a sound profile comparable to the OEM exhaust. In Loud mode, the valve opens, allowing exhaust to flow through the right-hand muffler, minimizing resistance and delivering a deep, powerful tone with maximum performance.
An electric servo, insulated from heat and fully weather-resistant, operates the valve. During tuning, our technicians customize the system primarily for Loud mode. We recommend using Quiet mode in urban areas.
Installation
The system comprises two titanium mufflers and link pipes that exit on the left and right sides, connecting to the OEM exhaust manifold. This exhaust itself is easy to install for a proficient mechanic however the wiring for the Bi-Modal button needs to be routed in a way to avoid electrical interference from the coils. Thus it is recommended a qualified technical install this exhaust.
APPEARANCE
The surface finish is a natural brushed titanium, which is resistant to staining, corrosion, and the need for polishing. Additionally, titanium is highly resistant to acid and salt and dissipates heat twice as fast as steel.
