Why Upgrade to the PLM High-Flow Catalytic Converter?

The PLM High-Flow 400-Cell Metallic Catalytic Converter is engineered for those who demand performance without compromising emissions compliance. This unit is designed to enhance exhaust flow, providing your engine with the breathability it craves for optimal performance. Whether you're a daily driver or a weekend warrior, this converter will help you experience improved engine efficiency and power delivery while remaining EPA compliant.

Fitment and Compatibility

When you're upgrading your exhaust system, especially if you're installing a PLM header or manifold, it's the perfect time to also replace your catalytic converter. This ensures maximum performance and exhaust flow, making it a crucial component for your setup.

Emissions Compliance

While this catalytic converter is EPA compliant, it’s essential to note that it may not be emissions legal in all states or jurisdictions. The federal regulations prohibit tampering with emissions control devices, so always check your local laws before installation. Our catalytic converter is designed to produce emissions that meet or exceed EPA standards, but ensure that your modifications align with local regulations.

Cell Density Explained: 400 vs. 200 Cell

Understanding the difference in cell density is crucial for performance tuning. This 400-cell cat means there are 400 cells per square inch, which allows for efficient exhaust flow while still providing adequate filtration. If you're looking for a balance between factory-like emissions and enhanced performance, this is the ideal choice. For those seeking maximum flow with minimal restriction, consider our 200-cell options.
