Our take on the PLM High Flow Performance 400 Cell EPA Metallic Catalytic Converter

The PLM High Flow is a universal 3-inch metallic catalytic converter with a 400-cell metal core, built for drivers who want to cut emissions without choking exhaust flow. Its 3.0-inch inlet and outlet and 7-inch overall length make it a compact weld-on or clamp-on replacement for tired factory cats on modified cars. The 400-cell metallic substrate flows better than a dense ceramic cat but cleans less aggressively than a stock unit, and it is EPA compliant but not legal in California or New York. Owners rate it well overall, though a few report fitment and durability issues.

Questions and answers

Is this catalytic converter legal in California or New York?
No. It is EPA compliant but not CARB approved, so it is restricted in California and New York and cannot be registered there.
Will it fit my car?
It is a universal 3-inch unit, so it fits cars with 3.0-inch exhaust piping. Most vehicles need welding or adapters, so check your pipe size first.
What is the difference between 400-cell and 200-cell cats?
A 400-cell core cleans emissions better than a 200-cell race cat but flows slightly less. It is a middle ground between stock and high-flow race units.
Does it pass emissions testing?
It is EPA compliant and passes testing in most states outside CA and NY, but a 400-cell metallic core may not satisfy strict tailpipe standards.
What is included in the box?
The converter itself. Clamps and adapters are usually not included, so plan on welding or buying hardware separately.
Will it increase power?
It can free up a little power on a tuned car by reducing backpressure, but gains are modest on a stock engine.
