Catted Downpipe

[NCspecV81]

I believe I read somewhere that your cell count was 200 on the cats? Is this right? Like I said I think I saw it somewhere before, but I can't seem to locate that info now.

Also, would the cat be usable in a high horsepower build? Let's say around 600-700hp?

The only thing I can find is it says "stainless steel honeycomb high flow cat". If you're aiming for 600-700 hp what's wrong with catless?

In NC, which I'm sure you are aware, we are allowed only 1 not ready code anything post model year 2000. Wanting to save that not ready code for something I may not be able to avoid in my build. Otherwise I would just run catless. So retaining a serviceable cat is very important to me.

I'm well aware of the inspection for the state haha. I've had a few cars barely get by. I run catless and haven't thrown a code for it luckily. I do have a downpipe with a hollow cat that I throw on just for visual if I have any problems. One thing you can do is find a station without a lift. That way they can't see really. Kinda playing the game/working the system.

I don't know of any inspection stations where you are. I have a few guys around here who will overlook certain things.

But yes, having the not ready in your back pocket for something you can't avoid is a smart idea.

Our high flow cats are 200cpi, but if you're going for that amount of power I wouldn't suggest using a catted. This is why we designed our atmosphere kits to come catless. The bigger turbo, aggressive tune and possible meth injection will eventually eat up the cat and it will fail becoming a warranty nitemare. That being said our catless dp comes with a defouler and you can adjust it so you will not get a cel of any kind, related to the dp. The defouler will pull your secondary )2 sensor out ot the stream. No ready code, no cat, win-win situation
