G-Sport Gen1 UHO EPA Compliant Catalytic Converter Core - 4.500" Body x 4.000" Long (85002)

The GEN1 Advanced series of Catalytic Converters is reinforced with our proven S-Wound Core and supports up to 2016 model year applications. GEN1 High Output (HO) models support up to 500hp per catalytic converter (or per exhaust bank) for vehicles up to the 2016 model year.

G-SPORT EMISSIONS SYSTEMS - DESIGNED FOR PERFORMANCE

Typical 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 GEN1 Advanced Catalytic Converters are designed with our 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 our ‘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 our high flow GEN1 Advanced Catalytic Converters with 300 cells per square inch (CPSI). Our advanced substrate design, combined with our proprietary wash coat nano-technology, ensures the highest level of emissions reduction with comparable flow rates of similar 200 CPSI converters on the market.

HOW DOES A CATALYTIC CONVERTER WORK? CHEMISTRY 101

Our 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.

NEW EMISSIONS REQUIREMENTS - NEW G-SPORT TECHNOLOGIES

For years G-Sport by GESi has addressed the needs of performance enthusiasts with well-built, emissions compliant aftermarket solutions. To date, our 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 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 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.

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!

G-SPORT EPA COMPLIANT TECHNOLOGY VS. NON-EPA COMPLIANT MODELS

G-Sport by GESi® prides itself on building the highest quality emissions solutions. To address the needs of performance enthusiasts all of our G-Sport models incorporate our C3 Process in constructing each catalytic converter with high-grade stainless steel inside and out. Our metallic core is furnace-brazed and held in place with our Double-lock technology to ensure it will not telescope like lower-quality solutions on the market.

The key difference between models is our EPA Compliant catalytic converters have been third-party lab tested to meet or exceed local emissions standards in North America (excluding California) and will address Check Engine light issues with proper engine setup.

Our Non-EPA models are built with the same high-end construction, but do not offer the emissions compliant coating to meet local regulations and will not eliminate the check engine light. These models are best suited in applications where a stock catalytic converter was not offered from the OEM (vehicle years 1973 and older) as well as any off-road application such as trail or race.

Comfortable Pillow!

For many years, I always bought the same brand latex foam pillow. Unfortunately, it's not made anymore so I took a chance with something new. I'm glad I picked this one! Very comfortable and I like the medium firmness. Not too soft or too firm, perfect for me. There is a very slight odor but it is not overpowering at all and I know it will dissipate over time. I will be purchasing another one soon!

A Good Night’s 💤
Size: Standard (Mid Loft), Number of Items: 1
I’ve bought many pillows over the years and this pillow is by far the best for me. I am a back and side sleeper. Finally wake up without a headache or neck discomfort. I bought the medium standard. Just the right consistency. Not to soft not to firm. Stay cool pillow.
