The high-flow 200-cell metallic catalytic converter increases exhaust gas flow, providing faster turbo spool-up, improved throttle response, and greater power. Unlike ceramic catalytic converters, the metallic core is more heat-resistant and durable, making it ideal for high-performance applications. The 100% stainless steel construction, combined with mandrel-bent piping and TIG-welded seams, ensures long-lasting durability and high-performance results.
