G-SPORT BY GESi®
Industry Leading High Performance Catalytic Converters
The GESi® Advantage & Our C3 Process
The GESi® Advantage & Our C3 Process
The GESi® Advantage stands for North American built emissions solutions with a focus on quality and performance.

Whether concentric or our NEW S-Wound technology, our Cores are designed with 304 Stainless Steel substrates that are furnace-brazed to provide long term performance and emissions control

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

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.

Don't sacrifice performance when it comes to emissions control.
