Metal Catalytic Converter Substrate E4 D120/100L 200cpsi

The Metal Catalytic Converter Substrate E4 D120/100L 200cpsi is a high-flow metallic catalytic core designed for catalytic converter rebuilding and professional exhaust fabrication. It is intended to be welded into an existing catalytic converter housing or muffler to help reduce harmful exhaust emissions while maintaining efficient exhaust gas flow.

This metal catalytic converter substrate is manufactured using advanced metallic honeycomb foil technology, offering improved durability compared to traditional ceramic cores. The metallic structure provides excellent resistance to vibration, mechanical stress, and high exhaust temperatures, making it suitable for performance vehicles and demanding operating conditions.

With a 200 cells per square inch (200cpsi) configuration, this catalytic substrate offers a balanced combination of emission efficiency and reduced backpressure. The 200cpsi density ensures sufficient surface area for catalytic coating while allowing smooth gas flow through the exhaust system. When properly coated with precious metals such as platinum, palladium, and rhodium, the substrate supports E4 emission compliance.

The D120 diameter and 100mm length make this catalytic core suitable for medium to larger exhaust systems. Proper selection requires accurate measurement of the catalytic converter housing diameter and internal length to ensure correct fitment and optimal performance.

Compared to ceramic alternatives, the metallic catalytic converter substrate heats up faster, improving cold-start emission performance. Its reinforced construction significantly reduces the risk of cracking caused by vibration or rapid temperature changes.

Is ideal for emission system restoration, custom catalytic converter manufacturing, and professional exhaust system upgrades.

Professional welding and correct catalytic coating are required to achieve full emission functionality.
