Designed for serious performance builds, the GESI G-Sport GEN1 300 CPSI Catalytic Converter is rated to handle between 500 and 850 horsepower. This unit is specifically engineered for high-output applications where exhaust flow is critical to maintaining power, yet EPA compliance remains a requirement for street legality.
The GEN1 series provides a reliable and effective way to manage emissions on high-boost or high-displacement engines. Its 300 CPSI substrate is optimized to provide the necessary catalytic reaction without restricting the massive volume of exhaust gas produced by high-horsepower setups. This converter is a favorite among tuners and builders who need to balance extreme power with environmental responsibility. The durable housing is built to withstand the intense heat associated with high-output engines, ensuring long-term reliability even under track conditions. Whether you are running a twin-turbo setup or a high-compression naturally aspirated engine, this GESI converter offers the flow and filtration you need. Its 4.5x4-inch design allows for versatile placement in custom exhaust systems. Don't settle for restrictive converters that choke your engine's potential. Choose the industry-leading GESI G-Sport series for your next build. Discover more high-performance exhaust parts at GGCRACING.
