Description

The GESI G-Sport Gen2 HO catalytic converter is engineered for performance enthusiasts, offering EPA compliance without compromising exhaust flow. It utilizes a durable S-Wound metallic substrate with 300 CPSI for effective emissions reduction. This converter is built using a proprietary wash coat nano-technology to achieve superior emissions control, comparable to 200 CPSI converters in terms of flow rates. The three-way catalyst technology targets Hydrocarbons, Nitrogen Oxides, and Carbon Monoxide, converting them into environmentally neutral byproducts through a process enhanced by precise transition cones and a triangle-based substrate pattern. GESI's GEN2 series is designed to meet updated emissions requirements for 2017 and newer vehicles, supporting up to 1,200 hp. The G-Sport models incorporate a C3 Process with high-grade stainless steel construction, both inside and out, and feature furnace-brazing and Double-lock technology to ensure longevity. This EPA-compliant model has been third-party lab tested to meet or exceed emissions standards in North America, excluding California, and can help address Check Engine light issues with proper engine setup.
