Item Summary

The Spark Exhaust GDU8854T Double Dyno Full System is a race-developed, full titanium exhaust engineered for Ducati’s latest V4 platform. Featuring dual undertail silencers, advanced Inconel connections, and significant weight reduction, this system delivers maximum performance, improved exhaust flow, and unmistakable race aesthetics for serious track riders.

About the Product

The Spark GDU8854T is a top-tier racing exhaust system developed specifically for the 2025–2026 Ducati Panigale V4 / V4 S and Streetfighter V4 platforms. Designed using knowledge gained from World Championship racing programs, this system represents a complete evolution in both performance and design.

At the core of the system is a full titanium collector assembly, paired with dual “Double Dyno” undertail silencers. This configuration optimizes exhaust gas evacuation while maintaining ideal flow balance between cylinders, resulting in improved throttle response, engine efficiency, and power delivery.

A key engineering highlight is the use of 3D-printed Inconel engine connections, an aerospace-grade material designed to withstand extreme heat and stress under racing conditions. Combined with a 5-axis CNC-machined 3-way compensator, the system enhances exhaust gas flow between front and rear cylinders for improved thermodynamic efficiency and engine performance.

Spark lists the system at 6.5 kg, compared to approximately 11.6 kg for the OEM exhaust, offering a substantial reduction in overall weight. This translates directly into improved handling, acceleration, and responsiveness—critical advantages for both track use and aggressive riding applications.

The system is completed with carbon fiber heat shields and carbon-accented silencers, combining functional thermal protection with aggressive race-inspired styling. As expected from Spark, the exhaust is fully manufactured in Italy, with a strong emphasis on craftsmanship, welding precision, and premium materials.

This is a non-homologated racing exhaust system, intended strictly for closed-course use. For optimal performance, Spark and distributors recommend ECU remapping to ensure proper fueling, throttle response, and long-term reliability.
