GESi® G-Sport High Output Catalytic Converters
Featuring full 304 stainless steel construction - including the
substrate - GESi® HO-Series Catalytic Converters are EPA certified in 49 states and fully OBD2 compliant, perfect
for use on 1996 and newer vehicles. GESi® proprietary precious metal loading technology ensures greatly reduced
emissions, eliminating most "Check Engine Lights". These high flow catalytic converters outperform stock converters
and provide a reliable solution to the most common catalytic converter problems.
The new G-Sport GEN2 Catalyst technology consists of an EPA-approved precious metal coated substrate which better adheres to the stricter emissions regulations on 2017 and newer model year vehicles.
Don't hesitate installing one of these on your custom exhaust system. The GESi® HO-Series Catalytic Converters are
rated for engines putting out between 350 and 500 horsepower while maintaining a high flow capacity. The reduced
back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the
harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!
Please Note: These catalytic converters are not legal for use on vehicles registered in the state of California as a
result of California Vehicle Code Section 27156 and 38391.

GESi® is a global leader in the design, engineering and manufacturing of emission control systems for all types of
fuel burning engines, whether it be spark, rotary or compression. Their emission technology has been industry tested
and proven effective for engines burning all types of commercial fuels, including gasoline, propane, natural gas,
diesel and bio-diesel.
GESi® is the brainchild of its co-founder and President/CEO, Eric Latino, a highly regarded Pro Mod drag racer and
current holder of the Canadian class record. He co-developed the proprietary emissions reduction technology that
sets GESi® catalytic converters apart from the competition. His goal was to offer a solution to owners of high
performance vehicles who simply could not find catalytic converters capable of consistently surviving the conditions
that those engines throw at them.
GESi® technology has been tested and verified in many applications, from as small as a gas powered lawnmower engine,
up to a natural gas co-generation plant. GESi® G-Sport Catalytic Converters will offer up peace of mind, reliability
and effective long term emissions control solutions. Say goodbye to Check Engine Lights and failed emissions tests.
G-Sport Chemistry 101
The G-Sport Emissions Systems Catalytic Converter is 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,
our 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 triangle-based substrate pattern that enhance flow
and residency time for optimal conversion and performance.
