Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b).

Increase exhaust flow by replacing the restrictive factory ceramic 750-cell catalyst for a high flowing German imported 200-cell HJS HD EURO 6 certified catalyst to unlock the ideal blend of performance, efficiency, and increased exhaust tone.

Fabspeed Motorsport is the largest distributor of premium HJS catalysts in North America, and second largest in the world. Based off years of engineering experience and worldwide testing we've selected the ideal catalyst to unlock performance from the factory exhaust system. This German imported 200 cell HJS HD catalyst is the top of the line solution to increase exhaust flow, resulting in a satisfying increase in turbo sound to match the extra horsepower gains. This specific catalyst has proven itself in numerous Ferrari and Lamborghini applications - able to withstand extreme abuse while preventing any check engine lights. The HD designation signifies the incorporation of a brazing stripe and special mantles to hold the metal matrix in place through the toughest of conditions while ensuring the overall integrity of the catalyst. The best part - increased performance without a check engine light and no tune required. All of this was 1st pioneered by Fabspeed research and development- as we got the worlds very 1st 718 Porsche 4 cylinder turbo and invested the time and resources to make Porsche people the best catalytic converter solution.

The portion of the exhaust that contains the catalyst is a rather large component, making a full replacement section costly. Our elegant "Slip-ON Design" design incorporates a OEM style Torca clamp for easy installation into the factory double walled exhaust configuration - simple cutting is required for installation. The 718 stock catalytic converter can easily and quickly be bolted on to make the 718 exhaust back to stock at any time utilizing the same OEM quality torca clamp. Its super simple and all completely hidden under the cars sheet metal covers. Its all undetectable. Simple cutting is the logical and smart way to accomplish a HJS German sport cat or catbypass pipe. If you 718 is ever in an accident Porsche AG specifies cutting and replacing exhaust components. Its logical.

The addition of Fabspeed's Sport Catalytic Converter added 8.5 HP and 18 ft-lbs of torque peak power gains when tested on our Dynojet on a stock vehicle. 13 whp and 17ft-lbs at 4000 will make a significant difference in drivability. We look forward to extracting even more power with our hardware in conjunction with a tune at a later date.

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Nice office chair
Color: Beige
I recently purchased this chair for my home office setup. This chair is very comfortable and feels sturdy right out of the box. The seat cushion is thick and supportive, the back provides good support. I really like the flip-up armrests, which make it easy to slide the chair under my desk. Assembly was simple and didn't take long. Overall, it's a solid, well-built chair and a great value for the price.

Stylish, comfortable, and very practical
Color: Black, Color: Black
This chair is both cuteand funtional. The wide seat is super comfortable, especially for sitting cross-legged, and the flip-up arms are really convenient. I also like the side pockets for small items. It rolls smoothly, feels sturdy, and was easy to asssemble. Perfect for a home office or vanity setup.

Seat width short (Not tall people friendly) Very nice otherwise.
Color: Beige
I like the chair a lot. It’s very sleek and modern. One problem I have with it tho is the width of the seat. I am 5’9 and not necessarily a petite woman and when I do sit cross cross I seem to hang off the front. I do like that I can sit cross cross even with the sides of the chair up but the fact that I hang off the front is a bit annoying. There are plenty of other ways to sit on it tho and being able to maneuver it to where I can sit different ways is nice. I would say that this chair isn’t exactly tall people friendly. Also pay attention to the height and width of your desk because it isn’t exactly universal to fit under a normal desk. It is also super easy to put together and instructions are clear. Also as expected the back of the seat is a bit short and personally for me I like that a lot but word of caution for others that want the back of the chair to go up their entire back. I like it shorter because I’m able to sit sideways and have one side of the chair up and the other down and using the back rest as an arm rest. I did just buy it and am slightly concerned for it to not last purely because the manual said not to use it if it squeaked of creaked and it does both of those things. But I will still be using it until it breaks or it’s life span ends. It also seems very easy to clean the crevices are very short and you are able to wipe things out with ease.

Really comfortable upgrade from my old desk chair
Color: Beige
My old desk chair had been getting pretty uncomfortable, so I decided to replace it with this white one. After using it for a few days, I can definitely say it’s been a really nice upgrade for my workspace. My old chair was starting to feel stiff and uncomfortable after sitting for a while. This one is a lot wider and softer, which I really appreciate. Sometimes I sit cross-legged when I’m working on my laptop, and this chair actually has enough space to do that comfortably. The flip-up arms are also really practical. When I’m not using them, I just flip them up and push the chair under my desk. My workspace feels a lot less cramped now. The wheels roll smoothly and the height adjustment was easy to set up. I also didn’t expect to use the side pockets much, but I’ve been keeping a notebook and my tablet there, which is actually pretty convenient. I mainly bought the white color because I wanted something simple for my home office, and it looks really clean in the room. After switching from my old chair, working at my desk has been a lot more comfortable. It’s been great for longer work sessions, and overall I’m really happy I decided to get this one.
