    Kinetix Racing High Flow Cats

    Getting good airflow isn’t about opening the windows. In order for your engine to fire at peak performance, you need an exhaust system that can pull out used up air efficiently and quickly, in order to get more air in. Unfortunately, most cars build a choke point into the exhaust system as a stock option — factory catalytic converters can ensure legal emissions, but they can slow you down and steal horsepower.

    Kinetix Racing has a brilliant solution for the Nissan 350Z and Infiniti G35 with its high-flow catalytic converters, which are engineered to draw out exhaust while remaining within legal emission levels. The trick is the stainless spun construction. Each converter is fully TIG welded with mandrel bends for the best possible air flow. They will easily bolt to any header and any exhaust, and are equipped with a factory oxygen sensor location — that means you won’t deal with pesky “Check Engine” lights.

    All of this adds up to incredible performance gains with only a slightly more aggressive exhaust note. In the battle of high flow catalytic converter vs stock, you’ll see a clear winner emerge — helping you become a winner on the track.

    Please Note:

    Lasted a while.

    I had gotten these test pipes September 2017 and they just went out this year. I do beat the car, overall they're a good set of cats. Sold the OEM cats to the scrap and got most of my money back.

    Everything went well

    I put these on my 2006 G35 coupe that had all stock exhaust/cats at 155k miles. My cats were plugged and bogging my engine down and creating all kind of problems. I went with these Kinetix hi-flo cats for a couple of different reasons. First was the price. These are some of the cheapest cats out there with better reviews than other cheaper cats, so I went with it. Second is that these are performance cats. I'm not exactly trying to make a race car, but i do a lot of highway driving at 75mph+. Ill be putting on a hi-flo intake in the near future to let the car breath a little more. One thing everyone needs to know is that these cats do not come with heat guards like whats on the stock cats. They align perfectly in to place, but they ride up a lot closer to your heat shields under your car. So close, in fact, that the next day I had to put it back on the lift and use a pry bar to bend the heat shield away from the cats. I had to do this on both sides. The heat shield is thin aluminum or something close, so it bends pretty easy. You don't need much clearance to get the raspy sound to go away. After that the car sounded great! I feel like these cats sound like stock, but just a little louder. Other than that, its been a little over 5k miles since I've put them in and still going strong. Its also probably a good idea to run a fuel and exhaust system cleaner every 2k miles or so, and run premium gas more often. I hear that these hi-flo cats can get clogged pretty quick. I will try to update in the future. If no problems arise, I will up this to a 5-star review.

    Excellent

    It came very quickly with proper protection for the product. The product was simple to install and did not bring a check engine light. As a car enthusiast I love the sound. It slightly changes the raw sound of the car and makes it 1.5 to 2 times louder than original. Overall great product and service!

    Kinetix Racing High Flow Cats

    They're alright I guess. Lot of rasp on cold start ups even after they've been on the car awhile now. Also have grinding noises from them rubbing against the heat shield despite having them adjusted once. I'll probably have to spend time doing it again soon because the it's annoying. I don't remember now if there was an option to add brackets like the factor cats but there should be if there isn't because that might help prevent them from rubbing. For people raving about the sound idk what they're hearing. It's just slightly louder really, and slightly more rasp if that's what they're into. No CEL light in fact mine went off after installing because my driver side cat was bad so that's a plus. After all of that I think these are just OK cats in my opinion.
