High Performance Metal Motorcycle Catalytic Converter Euro 4 5 6 Exhaust

Engineered for petrol-powered two-wheelers, this universal motorcycle catalytic converter delivers reliable exhaust treatment while maintaining strong engine performance. Built with a compact round metal honeycomb substrate and coated with active catalytic metals, it efficiently converts harmful carbon monoxide (CO) and unburned hydrocarbons (HC) into safer compounds, alongside reducing nitrogen oxides (NOx). Optimized for a 200 CPSI cell density, the 42 x 110 mm core responds rapidly to exhaust heat, making it an effective upgrade for riders aiming to meet Euro 3, 4, 5, or 6 emission standards during custom builds or system repairs.

Benefits & Practical Tips

• The metal substrate conducts heat faster than traditional ceramic units, allowing earlier catalyst activation during stop-and-city riding.
• Ideal for fabricating new exhaust runs or replacing failed units in standard street bikes and commuters.
• Tip: Always measure your pipe’s inner diameter and check under-seat clearance before cutting. A professional welder ensures there are no exhaust leaks that could skew air-fuel readings.

Warnings & Usage Reminders

This aftermarket core is strictly designed for petrol motorcycle exhaust systems and is incompatible with diesel engines, DPF platforms, or high-output sportbike configurations. Passing regional emission tests depends on fully tuned carburetion/injection mapping, functional oxygen sensors, and correct operating temperatures. Do not attempt DIY modifications if you lack welding experience; improper sealing can create safety hazards. For non-standard sizes or higher cell densities (100, 300, or 400 CPSI), custom orders require a minimum of 10 units.
