What is a high flow cat and how do they work? Chemistry 101

G-Sport high flow cats contain a three-way catalyst that reduces up to 99% of harmful exhaust emissions in vehicles. By targeting the three main exhaust gases - Hydrocarbons, Nitrogen Oxides and Carbon Monoxide - GESi's proprietary wash coat technology of precious metals separates the toxic compound structures to create environmentally neutral Water, Nitrogen and Carbon Dioxide as byproducts.

This process is enhanced by G-Sport’s precise transition cones and S-wound substrate pattern that enhance flow and residency time for optimal conversion and performance.

What makes G-Sport emissions better?

GESi high flow cat systems are built to deliver the best of both worlds in terms of performance and emissions, arguably one of the best high flow catalytic converter options for well-rounded use on the market. While maintaining or exceeding factory performance, you can expect to see up to:

• 99% reduction of carbon monoxide (CO) emissions
• 98% reduction of nitrogen oxide (NOx) emissions
• 95% reduction of hydrocarbon emissions

Typical hi flow catalytic converters include ceramic substrates that have a higher rate of cracking, degradation or cause too much back pressure in vehicle exhausts. G-Sport Emissions Systems High Performance Advanced Catalytic Converters are designed with their proven S-Wound metallic substrate for added durability. The substrate is then lined with nickel strips, and furnace-brazed to provide a solid bond throughout the core and to its mantle. This process, and their ‘Double-Lock’ transition cone application, ensure the core will not telescope or fail in high performance environments.

For best emissions control capabilities without performance degradation, G-Sport designed their GEN1 Advanced high-flow catalytic converters with 300 cells per square inch (cpsi). This design, combined with their proprietary wash coat nano-technology, ensures the highest level of emissions reduction with comparable flow rates of similar 200 CPSI converters on the market.

What is the difference between G-Sport GEN1 and GEN2 catalytic converters?

For years, G-Sport by GESi has addressed the needs of performance enthusiasts with well-built, emissions compliant aftermarket solutions. To date, their existing GEN1 line has provided emissions compliance and addressed check engine lights while maintaining the performance levels required in forced-induction applications in vehicles up to the 2016 model year.

With the updated emissions requirements in 2017 and newer vehicles, G-Sport by GESi has developed a new GEN2 catalytic S-Wound 400cpsi core design with an updated proprietary precious metal coating. The new proprietary coating addresses the latest emission standards in newer vehicles while providing support for up to 1,200 hp with increased OD sizes of up to 6 inches, as opposed to the GEN1 maximums of 850 hp and 4.5 inches respectively.

Introducing the latest technology and product enhancements – our Advanced Series lineup now includes our proven S-Wound core technology in both GEN1 and GEN2 with new emission control solutions including Diesel Oxidation Catalysts and Mid-bed Catalytic Converters coming soon!

What is the G-Sport C3 Process?

Quality and performance have always been GESi's top priorities. All of their performance catalytic converter line is carefully managed during all three key C3 Processes – Core, Coating and Canning. Each stage is supervised to provide the peace of mind that your emissions systems will perform better and cleaner than ever.

The Core process begins with quality metallic foil that is rolled to form the S-Wound cell design. Each cell is constructed to an exacting dimension that balances exhaust flow, with effective emissions conversion. GESi achieves strength and durability in their hi flow cat cores by lining each layer of foil with nickel and furnace brazing the entire assembly together to its mantle. The construction process ensures that every GEN1 or GEN2 Advanced G-Sport Catalytic Converter is capable of handling the flow produced by today’s high horsepower applications.

All GEN1 and GEN2 Advanced GESi sport cat cores feature G-Sport's proprietary wash coat that is designed to form a strong molecular bond with metallic surfaces. Confidently choose G-Sport knowing that your high flow cat converter has coatings durable enough to withstand the high temperatures (up to 1,700°F / 925°C) flowing through high performance exhaust systems.

In-house canning processes ensure that this entire solution is ready for use by GESi's manufacturing partners as well as performance enthusiasts. Double-Lock technology ensures that the catalytic core and mantle are fused together, ready for integration into your high performance exhaust system.
