Universal Metal Catalytic Converter For Car Exhaust 300CPSI Three Way
Engineered for reliable exhaust management, this universal metal three-way catalytic converter delivers optimized emission control alongside improved gas flow. Constructed from a durable metal casing and calibrated to Euro 4 standards, it handles 300 cells per square inch (CPSI) to reduce backpressure while filtering pollutants effectively. Measuring 107 mm in diameter and 120 mm in length, the compact unit accommodates straightforward retrofit installations where original equipment fails or is unavailable. Its neutral packaging and adaptable geometry make it a practical solution for mechanics and DIY enthusiasts seeking a dependable, high-throughput alternative that restores proper exhaust function without compromising engine responsiveness.
Benefits & Practical Tips
The 300 CPSI metal substrate balances filtration efficiency with reduced exhaust restriction, helping maintain stable idle quality and throttle response during everyday driving. When fitting, align adjacent piping carefully and allow minor positional adjustments to secure clean joints without stressing the mounting points. This converter performs best when paired with intact oxygen sensors, heat shielding, and proper welding or high-rating bands to preserve system integrity.
- Verify flange spacing and inlet/outlet angles before purchase to ensure direct interchangeability with your existing exhaust routing.
- Avoid combining this unit with aggressive downpipes or oversized aftermarket pipes, as excessive airflow will bypass the catalyst surface.
- Inspect gaskets and mounting hardware during installation to prevent heat-related leaks that can trigger sensor codes.

Installation & Compliance Reminders
This converter is intended to restore regulatory emission standards while supporting moderate airflow gains for stock or mildly tuned vehicles. It is not recommended for heavily modified platforms with significantly elevated horsepower unless specific engineering parameters are reviewed. A manufacturing dimensional tolerance of ±0.05 mm ensures standard fitment and does not affect sealing or operational performance. Always confirm local motor vehicle regulations before retrofitting exhaust aftercare components.
