Eastern High Performance Catalysts

Exhaust system backpressure is a physical resistance that the cylinders in the engine must push against on the exhaust stroke. Reduce the backpressure and you’ll produce more power. Eastern High Performance Catalysts reduce backpressure by using bigger cells or more cells than standard converter catalysts (cells are the openings in the catalytic substrate that let gases flow through). Eastern Performance ceramic catalysts are available with 300 cells or 400 cells per square inch. Our full metallic foil catalysts have 200 cells per square inch, and their metal construction withstands extreme pressures and vibration that can crumble standard ceramic catalysts.
