Kinetix Racing High Flow Cats | Nissan / Infiniti Multiple Fitments (KIX KX-DE-HFC)
Kinetix RacingKinetix 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.

Customer Reviews
My passenger side cat was bad so I replaced both with these high flow cats. The car feels more powerful now and runs better too. There’s no cel light either. It does have rasp on cold startups, but it goes away while driving. I do like the sound it gives to the car, I hope these last for awhile.
would these fit a 04 G35x AWD
Saved 1400 dollars by not using mechanics parts. Surprising return of performance after install. Thanks
Works great and pleased with results i recommend.one note be sure and run thread chaser thru each 02 sensor bung before inserting sensor. Other than that great buy for my 350z.

Great fit & build quality for my 03' G35 coupe.
Slightly deeper exhaust note.
Very noticable power increases, feels like an easy 20+ hp!!!
