Cats or No Cats

[1320junkie]

Who has cats and doesnt have them with your Longtube set up? Why or why not?

Are emissions the only factor for you?

Junkie,
Dont have the setup on the car YET, but my setup will the ARH longtubes, non-catted x-pipe, DMH cutouts, into Borla Stinger-S system.

I like noise!! Only issue I will have is noise violation potential with local LE and issues getting vehicle inspection (my county in texas DOES NOT do an emissions test but still will check under the car if the suspect the cats have been removed)

This is also not necessarily my daily driver, so i'm not worried bout it!

I always run high flow cats on my cars due to emissions. Expect for my real old stuff.
I didn't check yet , but do they make high flow cats for long tubes on the camaro?

Cool, thanks for your reply. Atlanta has emission standards but down in south georgia there are none. I have a property I rent out to someone there so thats what I use for my tags etc.

I dont know if they do or not. I just ordered my longtubes last week without cats.

I'd be too worried about emissions to take off the cats.

Besides, who could say no to this?

Meow, I have a ca......oh, nevermind.

What about federal emission laws?

Catalytic converters have catalysts—hence the name—in them that make harmful exhaust gasses less harmful. Without them, the car would emit gasses that would cause the car to have poor or failing emissions ratings in most, perhaps all, states. Technically, you're not allowed to change the catalytic converter, to my knowledge, within 5 years, but that has never stopped anyone.

I run long tubes and a catless x pipe on my C5 Corvette. Even with a stock catback it is very loud, at least for my taste. When I had the Borla Stingers on there it was absolutely unbarable. And of course you dump raw fuel which can be a little intoxicating warming up your car or sitting at lights.
I am putting ARH longtubes w/ cats on the Camaro next week so I will have a good idea of the differences shortly. Never had cats on the Vet so not sure how much difference it will make yet.

OP: cat removal is a federal issue, statewise and locally, every place has their own emissions standards and testing, but legally...cats have to be there...if there is a visual check you could face a fine..I think last time I looked, it's pretty steep. Not worth at least having high flow cats, it's only a couple of HP difference.

Yep, 5 years or if said cat is found defective, which, according to every warranty I've read, is replaceable under the federal 8 year/ 80K mile waranty.

I have Kooks HF cats. Why? Not sure why, I live in a non emmission state. Thought about the offroad pipe. But I went with the cats and now I am getting the lean code bank one and 2. Of course this only happens when I fogg the Sh!t ot of it. Questioning, my decision, will see what happens once I get the fuel trims reduced a tad.
