- Two “Gunshot Dark Matter” silencers in an under-seat configuration for a pure superbike look.
- Integrated exhaust valve - control over the distinctive sound.
- Complete mounting kit including carbon heat shields.

For the owner of a Ducati Streetfighter V4 who does not simply want to fit another exhaust, but wants to upgrade to something special, there is this complete exhaust system from QD Exhaust: it gives your motorcycle not only an intensely sporty appearance, but also technical benefits. Thanks to the hand-welded stainless steel exhaust headers, the under-seat configuration with two silencers, and the integrated exhaust valve, it is ready for both track and performance-focused use.
Installation is plug-and-play for those with experience - remove the standard exhaust and headers, install this system in their place, and use the original mounting points. Please note: because this is a racing product, ECU remapping is required for optimal operation. An ECU module can be ordered separately as an option. The result: immediate throttle response, significant weight savings, and a sound that perfectly complements the aggressive lines of the Streetfighter V4.
Technically, this system is an absolute masterpiece: the exhaust headers are manufactured from AISI 304 stainless steel and fully TIG-welded for maximum precision. The exhaust silencers are positioned under the seat, contributing to a compact, balanced look and optimal weight distribution. The integrated exhaust valve makes it possible to adjust the volume and character of the sound via the original servo or manual control, ideal for both road and track use. Thanks to the low total weight of approximately 4.2 kg - a significant saving compared with the original exhaust - the engine responds noticeably more sharply and the V4 steers even more lightly.
Frequently asked questions & answers
Does this exhaust fit my Streetfighter V4 (2025)?
Yes - this system was specifically developed for the 2025 Streetfighter V4 model and includes all the necessary mounting components.
Do I need mapping or additional hardware after installation?
Yes - because this is a complete racing system, ECU remapping is required to ensure the correct fuel-to-air ratio and optimal performance.
Is the sound suitable for road use?
The exhaust was primarily developed for performance purposes and has a distinctive, raw character. For road use, a dB Killer or custom mapping may be desirable to remain within local noise limits. The system is not E-approved, so no homologation documents can be provided.
How much weight savings can I realistically expect?
At approximately 4.2 kg, this system is much lighter than the original exhaust. You will feel the difference immediately during acceleration, braking, and rapid changes of direction.
With this upgrade, you are choosing a no-compromise combination of design, technology, and performance - an exhaust that perfectly complements the brute force and elegance of the Ducati Streetfighter V4. A statement for those who want to experience technology and emotion in perfect balance.
