Universal Cat 2in2out In-63 L400 E4 400cpsi Ceramic

Universal Catalytic Converter 2in2out – 400CPSI Ceramic Core E4

Universal Catalytic Converter 2in2out is engineered for dual exhaust system applications where balanced gas flow and reliable emission control are required. Designed with a 2 inlet and 2 outlet configuration, this catalytic converter is ideal for custom fabrication projects and performance-oriented exhaust systems.

The internal 400 CPSI ceramic substrate provides a high cell density for efficient exhaust gas treatment. Because of this structure, the converter effectively reduces harmful emissions such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). As a result, it helps vehicles meet environmental requirements while maintaining stable exhaust performance.

This model complies with E4 emission standards, making it suitable for vehicles that require certified emission control components. It is commonly used in custom builds, dual exhaust conversions, and replacement applications where a dual-flow catalytic solution is necessary.

With an inlet diameter of 63 mm and total length of 400 mm, this catalytic converter is designed for 63 mm exhaust systems. The 2in2out configuration ensures equal exhaust distribution, which supports smoother flow characteristics in dual pipe systems. However, professional installation is strongly recommended to ensure proper alignment, sealing, and welding quality.

The durable steel housing resists high exhaust temperatures and external corrosion. In addition, the ceramic core is built to withstand standard automotive operating conditions. When installed correctly, the converter provides long service life and consistent emission reduction performance.
