Hi-Flow Metal Matrix 200 Cell Catalytic Converter

The Hi-Flow Metal Matrix 200 Cell Catalytic Converter from Stainless Works is engineered for automotive enthusiasts and performance-focused mechanics seeking maximum exhaust flow without sacrificing emissions compliance. This high-performance converter replaces restrictive OEM units that rob horsepower and throttle response, making it ideal for naturally aspirated engines, mild builds, and street applications where both power gains and legal operation matter. The 200-cell design represents the sweet spot between flow efficiency and catalytic surface area, delivering improved spool characteristics and top-end power delivery compared to standard converters.

The metal matrix substrate construction uses durable stainless steel construction throughout the core and shell, resisting thermal stress and corrosion from aggressive fuel mixtures and extended heat cycling. The 200-cell configuration significantly increases the surface area available for the precious metals (platinum, palladium, rhodium) to facilitate the catalytic reaction, ensuring oxides of nitrogen, carbon monoxide, and hydrocarbons are efficiently converted while maintaining superior gas velocity. The hi-flow design minimizes back pressure, a critical factor in naturally aspirated engines where every psi of restriction translates to measurable power loss and turbo spool delay in forced-induction applications.

This converter suits street and light-duty racing applications where OEM certification or emissions testing is required—the 200-cell design passes most emissions standards while delivering genuine performance improvement. Installation is straightforward for vehicles with bolt-on or welded converters; verify your specific model's mounting configuration and flange size before purchase. The 3.75 lb weight and compact 10.55 x 6.7 x 12.45-inch envelope allow this unit to fit most mid-size exhaust systems without modification, making it a bolt-and-go upgrade for intake, cam, and tuning modifications on lightly modded builds.
