Ultimate Racing Ceramic High Flow Cats
Absolutely the best quality cats on the market! These high flow cats are made by Carsound, and are the best money can buy. Made of 304 stainless steel, these direct bolt on high flow cats retain the stock 02 sensors, and will not trigger a check engine light. Inlet and outlet is 2.5 diameter, making them a great choice for NA or forced induction setups. Cats meet or exceed all 50 state emissions requirements! These fit the 2002-2006 350Z and G35 coupe/sedan (does not fit "X" model"), or 2007 + models.
The ceramic core units are best suited for engines making up to 450 (crank) horsepower, and particularly well suited for NA use. They flow better than stock cats, though not quite as well as the Ultimate Racing metal core types. They will emit a nice, deep sound, and minimal 'rasp' compared to metal core type.
*Gaskets not included - we recommend OEM Nissan gaskets.

Ultimate Racing Metal Substrate High Flow Cats
New!!! These are the latest offerings for the Z and G from Z1 and Ultimate Racing - Metal Substrate High Flow Cats!!! The primary advantage to metal substrate vs traditional ceramic are the better flow characteristics and improved durability. All stainless construction, prewelded 02 bungs, and mounting hardware is included. We highly recommend getting new gaskets from your Nissan dealer as well. Fits all 2003-2006 350Z, and G35 coupe and sedan (except the AWD versions), or 2007-2008 models.
The metal core units are best suited for engines making up to 750 (crank) horsepower, and particularly well suited for NA or Forced Induction use. They flow better than stock cats as well as better than the ceramic core type. They will emit a deep sound, though due to the metal design, are higher pitched vs the ceramic core type. A great choice if you want the flow of test pipes, but don't want to deal with the smell, or noise associated with them.
*Gaskets not included - we recommend OEM Nissan gaskets.
