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 high-performance street configurations.
Unlike industrially stamped products, the DBR SilentX is made from thin-gauge P04 iron, using a fully hand-hammered welding technique that eliminates internal imperfections. The smooth internal duct optimizes gas flow, ensuring explosive power at high RPM, while the aluminum silencer reduces noise without compromising performance.
Available Finishes
- Exposed Iron (Racing Raw): “track-style” look with exposed welds. Requires maintenance with protective oil after use to preserve the iron and prevent natural oxidation.
- Cerakote™ Treatment: professional ceramic treatment that protects the iron from corrosion and extreme heat, with no need for external maintenance.
