Vandemon Ducati Diavel S 1260  – Bimodal Stealth Titanium Cat-Delete Slip-On

Years: 2016–2023

Experience the best of both worlds, stealthy silence and exhilarating sound, at the press of a button. Designed specifically for the Ducati Diavel 1260/S, the Vandemon Bimodal Stealth Titanium Slip-On eliminates the bulky OEM catalytic converter and heavy steel mufflers, replacing them with a lightweight, performance-focused titanium system that lets you instantly switch between two exhaust tones: Quiet Mode or Loud Mode.

Two Exhaust Personalities. One Button. Total Freedom.

With noise laws tightening worldwide and riders wanting more control over their sound, Vandemon created a breakthrough variable-valve bimodal slip-on.
This system lets you choose:

🔇 Stealth Mode – Quiet Tone

Perfect for early-morning departures, suburban riding, or long highway cruising.
The valve closes and directs exhaust flow through the large central muffler, giving a tone similar to stock, refined, discreet, and neighbour-friendly.

🔊 Open Mode – Loud & Powerful

Hit the switch, and the valve opens fully, allowing exhaust to exit through all three mufflers.
Up to 90% of gases take the least restrictive route through the lower muffler for maximum flow, maximum horsepower, and a deep Ducati growl.

A heat-insulated, weather-resistant servo motor controls the valve for reliable performance in all conditions.

How It Works

• Stealth (Closed Valve):
  Exhaust is routed through the central muffler and exits via the top outlet for the quietest possible tone.
• Performance (Open Valve):
  Exhaust flows freely through all three mufflers with minimal restriction—ideal for spirited riding outside city limits or during tuning.

Important:
When tuning, the map is optimised for Open Mode.
Stealth Mode should only be used for low-RPM, light-throttle cruising, as it is more restrictive at high engine speeds.

Pure Titanium Performance

Vandemon exhausts are engineered for riders who demand the absolute best:

✔ Massive Weight Savings

Titanium construction dramatically cuts weight for improved handling and acceleration.

✔ Lower Heat Retention

Titanium dissipates heat twice as fast as stainless steel, protecting bodywork and reducing heat soak while stationary.

✔ Exotic Weld Quality

Our unique welding process creates perfect, fully-penetrated fishbone welds—beautiful, strong, and made to impress Ducati purists.

✔ Irresistible Colouration

The natural brushed titanium finish turns stunning blue-and-red tones when heated, without staining or corroding.

Manufacturing Excellence

Every Vandemon exhaust is built using advanced engineering methods and premium-grade titanium.
Our welds are:

• Ultrasonically perfect
• Fully penetrated
• Visually flawless with a fishbone texture Ducati lovers admire

This is craftsmanship worthy of the Diavel’s iconic design.

Tuning

A custom tune is recommended for optimum performance and safe air-fuel ratios.
Open Mode is the basis for tuning, ensuring maximum power gains.

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.
