Codes with kooks "green" cats?

Kooks Headers · Sep 16, 2014

The number would be on the cat itself. Here is a picture of our GREEN cat.

I'm looking to put on kooks headers but now I dont wanna go green or highflow. Might just put on my OEM cats.

Either go with shortys and cat deletes or LTs and pay someone for a sticker. A properly tuned performance/muscle car does not need cats. Cats have nothing to do with clean air anymore, its all about the feds pockets lined with $$$ and so called highflo and green cats to make even more $$$. I use Kooks and Jegs and worst case scenario is i put back the cats and drive through the dmv. I should have went with LTs but the difference betw the shortys and LTs is less than 8 HP

We are working on this. The strange thing is we have several cars Boss and GT's running our GREEN cats with no codes.

The advantage of the GREEN cats does go beyond the no CEL part. These cats come with a EPA number on them and are 49 state legal for emissions testing. The biggest reason to go with the GREEN cats would be the flow. Our new GREEN cats flow as well as no cat at all. We have done extensive testing and have seen this on the dyno. Brenspeed even runs our GREEN cats on their race cars because of these flow characteristics.

Kooks,

Your exactly correct BRENSPEED does run your Green Cats.

In fact I just dropped off my 2008 Bullitt Mustang to them on Monday and they are installing your complete Kooks 1 3/4" LT Headers, Green Cats, Mid pipe etc.

I already have your smaller Kooks LT Headers, high-flow H-pipe and older high flow cats.
