Vandemon Stealth Bimodal Quattro Titanium Exhaust System for Ducati Diavel V4

Choose from two exhaust tones at the Press of a button

Vandemon has introduced the Diavel V4 to our Stealth exhaust catalogue in response to increasingly stringent global regulations and heightened public scrutiny. The entire exhaust system is constructed from lightweight, exotic Ti1 Titanium, reducing weight by 9.8kg. Additionally, we have incorporated a Bimodal variable muffler that allows you to switch between quiet operation and straight-through unrestricted exhaust, providing an unimpeded flow for maximum power and exceptional sound through four straight-through outlets. This exhaust system replaces the OEM steel mufflers, resulting in significant weight reduction and eliminating heat stress for riders in summer caused by heat emanating from the exhaust when stationary. 

Tuning 

Custom tuning is required as we do not provide a tune with our exhaust systems. You will need to employ a technician, preferably with a dynamometer, who will customize the tune for the open valve (loud mode), which will work fine in quiet (Stealth mode) also. Stealth mode should only be used when highway cruising or in suburban and city areas, at lower engine speeds and not when racing. The exhaust is designed to provide both performance and a quieter option, so the rider can choose between the two by pressing a button."

Vandemon exhaust systems are designed to deliver peak performance, style, and an impressive sound. They are crafted using advanced manufacturing techniques and high-quality materials like Titanium, resulting in a much lighter exhaust system with lower heat retention compared to the standard OEM system. The weld quality is exceptional, featuring ultrasonically perfect welds that are expected and appreciated by Ducati customers for such an iconic motorcycle brand that only enhances this outstanding marque.

Appearance:
"The surface finish is a natural brushed finish. When heated, it changes to an iridescent blue and red. Titanium has an advantage over stainless steel because it won't stain, corrode, or ever need polishing. This is due to Titanium's high acid and salt resistance, which also allows it to dissipate heat twice as fast as steel. This further safeguards against extended heat soak into body panels when stationary."

Manufacture:
We at Vandemon utilize a unique welding process that fully penetrates and creates an ultrasonically perfect connection at all joints with a distinct flush finish.

Tuning:

Custom tuning is recommended for the best results and to prevent a lean A/F ratio.

Why buy a titanium exhaust?

Due to its strength, weight and anti-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 and F1 and MotoGP

Other advantages of Titanium:

• Very light, Increased power too weight ratio
• Won't corrode or discolour
• Never need polishing like stainless steel & aluminium
• Dissipate Heat twice as fast as Stainless Steel
