G-Sport Gen1 HO EPA Compliant Catalytic Converter Core - 4.000" Body x 4.000" Long (50002)

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.

Not worth it
Size: Mini
The orange clasp that locks it in place is super faulty on the one I received. It folds at any point when trying to throw the ball. Not sure if I just got a defective one but I wasn’t a fan. Would rather get one at a pet store just to play it safe

Not as sturdy as a regular one
Size: Mini
I was holding off writing a review about this because I wasn’t sure that it was going to hold up as well as a regular non bendable Chuck It wand. I have found I like the way it folds up and fits into my backpack nicely and also fits into my big purse when I’m out and about with my dog. You have to make sure the orange sleeve is over the screw part in the middle of the wand before you can throw the ball otherwise it’s not going to throw. It’s going to collapse. I’m not sure how long the durability is going to last that’s my only question about this product and I don’t know how long the screws on the elbow of it are gonna hold up but for now it’s been working great and we play with it every day and I’ve not had a problem with it. It’s just not as sturdy as a full size wand

Love this version of Chuck It beyond all before
Size: Mini
I had the longer bendable Chuck It before, well several, which broke down. They finally wouldn’t’ release the ball. Not disparaging Chuck It. They have been my furry puppy's favorite thing ever. I am grateful. But what I like and think is intuitive about this smaller design is 2 things: 1. I can do a more dynamic throw. 2. There are circle holes in the Chuck It Ball that come with it that I think allow for easier release and the ball can go father. Just my two cents.

Still Good to Use in a Pinch
Size: Mini
Love the Chuck it brand. This collapsible one is not my favorite. Everytime I chuck it, the orange lock does not stay in place. Plus, in my opinion, it doesn't have the oomph for the distance like the other medium ones. Still good though

Best toy, the end
Style: Sport, Size: 12in, Style: Sport, Size: 12in
Combined with the Max Glow ball, this is the best dog toy available on modern planet Earth. I have a burly 92lb. pit bull mix with highly developed prey drive, and she will chase the glow ball for hours if I let her. The tiny sport launcher (Sport 12M) is the best, because you can still throw the ball really far, but you can also slam the ball down a few feet away from yourself so it bounces up in the air and your dog has to jump to catch it, or you can throw it up really high so it bounces 15' away or so and your dog can jump to catch it. We sometimes have to play fetch in a pretty small area, so it's nice to have the small launcher for these games. The larger launchers aren't as fun in small areas. You can play the same games but it's trickier to throw the ball correctly. Also, the small launcher is a lot easier to carry. The small launcher fits in my dog-walk-stuff backpack (with the ball in the launcher so I don't have to dig for it later), but the big ones don't easily. The launcher also has a hole in the end so you can hang it from your bag or whatever with a carabiner. The big ones are too long for that in most cases, and swing back and forth. Also-also my dog loves to ask for the launcher, then when I give it to her she plays keep-away and it's adorable. The big launcher I have is harder for her to balance in her mouth, so she just lays down and chews on it until it gets taken away. She's chewed on all of the four Chuck Its we've owned, but she's only broken one (a big one), but that's because she got ahold of it when no one was home. The little one in my bag is totally chewed up but still works great. I think they're sturdier than the big ones. Except for the launcher she chewed into pieces, which was our fault, the only reason we've had to replace anything was because we lost it. Usually we keep the launcher and ball in the backpack so she can't get to them and so they don't get lost, so we rarely have to replace them. There is just not a better value in toys, and the startup price is really low. Once again I really recommend the glow ball! It doesn't get soggy no matter how wet the grass or the dog mouth is. It is fun to chase because it is slippery and it collapses when it's squeezed, so it pops out of the dog's mouth and flies away if they bite it at the wrong angle; it's really bouncy, and stays bouncy because it can't be popped; it whistles so you can usually hear it even if you can't see it; and it really glows enough for nighttime catch, even if you only have your cellphone flashlight to charge it up! UPDATE: I should have said, we have the 12M launcher, which means the handle is 12 inches long and it uses a medium-sized ball. The medium ball is 2.5 inches in diameter, so the launcher will fit regular tennis balls, too! But my dog won't play with regular tennis balls anymore because they aren't anywhere near as fun as the glow balls, and I think she doesn't like having gross sloshy muddy tennis balls in her mouth. I lost my short launcher awhile back and could only get a long one locally to replace it, which reminded me that you have to lean over a lot further to use the short launcher. So if you have trouble leaning over to the point that your hand is a foot above the ground, this may be hard for you to use. I wish Amazon would let us choose colors, because my old one was green, and the big one is orange, both of which are bright enough to see in the grass from far away, even at night. Still, best toy!
