PLM high performance catalytic converter is made with a highest quality 400 cell, metallic catalytic core, ideal for both all motor and turbo applications.

When you install one of the PLM header or manifold, it is a good time to also replace your catalytic converter for maximum performance and exhaust flow.

400 cell vs. 200 cell?

A catalytic converter (CAT) is made of many little cells with high value metals which will take care of oxidizing the gazes that were not fully oxidized in the engine.  A 400 cell cat means there are 400 of these cells per square inch.  As this number goes down, the amount of physical cells decreases therefore generating fewer constraints for the exhaust flows.

We recommend this 400 cell catalytic converter if you want to retain factory-like emissions and have better performance, and in most cases, will not throw a code.

If you want high flow, with the least amount of restriction, we recommend our 200 cell catalytic converters.  See this link here.
