INTRODUCING
G-SPORT BY GESi®
Performance Without Compromise
The GESi® Advantage offers North American-built emissions solutions that prioritize the highest quality and performance.
As a leader in EPA-compliant emissions control systems, our expertise lies in manufacturing high-flow metallic substrates, developing and applying our advanced in-house precious metal coatings, and performing in-house substrate canning. Our comprehensive, end-to-end process delivers premium, high-performance catalytic converters designed for aftermarket applications. We have defined this as our C3 Process.
The GESi Cat Advantage & Our In-house C3 Process
S-Wound Metallic Core
Our proven S-Wound substrate technology is now available in both the Gen1 & Gen2 High-Flow Catalytic Converter product lines. These metallic substrates are furnace-brazed to provide long-term performance and emissions control.
Proprietary Wash Coat
Our in-house coating process includes our proprietary wash coat technology for GEN1 or GEN2 applications, designed to form stronger molecular bonds with metallic surfaces while maintaining performance and emissions control.
Double-Lock™ Canning
In-house Canning features our Double-Lock technology to ensure the catalytic core and mantle are locked in place, with core-only models now available up to 6″ OD, ready for custom exhaust integration.
