Industry-Leading High-Performance Catalytic Converters

The GESi® Advantage represents North American-built emissions solutions emphasizing the highest quality and performance.


As a leader in EPA-compliant emissions control systems, we specialize in manufacturing high-flow metallic substrates, applying advanced precious metal coatings, and in-house substrate canning. Our complete, end-to-end process delivers premium, high-performance catalytic converters designed for aftermarket applications. We have defined this as our C3 Process.



The GESi Advantage & Our C3 Process

C3 icon - G-Sport Core NEW

Our proven S-Wound substrate technology can now be found in both Gen1 & Gen2 Advanced Catalytic Converter product lines. These Metallic substrates are furnace-brazed to provide long term performance and emissions control.

C3 icon - G-Sport Coating new

Our Coating process includes proprietary wash coat technology based on GEN1 or GEN2 applications that are designed to achieve stronger molecular bond to metallic surfaces with performance and emissions control in mind.
