DBR SilentX is the racing exhaust designed for Vespa PX 170cc - 190cc engines, combining high performance with effective noise reduction thanks to the aluminum silencer. Made for those seeking optimized fluid dynamics and precise resonance, even in advanced street configurations.
Unlike stamped industrial products, the DBR SilentX is built from P04 Steel with reduced thickness, using a fully hand-peened welding technique that eliminates internal imperfections. The smooth internal channel optimizes gas flow, ensuring explosive thrust at high revs, while the aluminum silencer reduces noise without compromising performance.
Available Finishes
- Raw Steel (Racing Raw): “track-ready” look with visible welds. Requires maintenance with protective oil after use to preserve the steel and prevent natural oxidation.
- Cerakote™ Treatment: professional ceramic coating that protects the steel from corrosion and extreme heat, with no external maintenance needed.
