C6 but I have the opposite perspective, LS7 cats never gave me any issues, multiple 1/2 mile events, etc. No issues. Maxed out ECS kit, meth, 93 originally then switched to E85. Everyone said they wouldn't last but so far they have. Aftermarket LT cats have survived also, though it's clear they aren't nearly as effective as the factory stuff. Still stink for a while when cold and a little bit even when hot.
I'm sure eventually they will cause issues but I would rather have issues than smell all the time. I'm super sensitive to exhaust smells for whatever reason so for me, I prefer having them

If you are going to exceed that power level I would go catless, if cats are required due to emissions you can run the KOOKS green cats or the Vibrant GESi cats. Neither of those should fail, even with high HP applications.

It really depends on the power level, not necessarily the mods. The ARH cats are tough, but they do have a limit. Around 650-700rwhp is usually the max power output you can flow through those cats before you run the risk of them failing.

The ARH and standard KOOKS cats are of equal quality. KOOKS however, does offer their upgraded "Green Cat" which you can make 1000hp through. Cost for Green Cats is around $800 pair.

I don’t know that I would be concerned about only the cats themselves failing. It’s part of a bigger picture. If the cats gets too hot at melt, they can clog the exhaust and block the passageway for exhaust getting out. Which can cause major engine failure. For that reason I pulled my cats.

As you can see above I gave an emission compliant option to the person that was asking for advice. If he chooses to go that route, then so be it.
I am probably one of the more the environmentally conscious car enthusiasts you will meet. Rather than trolling me, or the company I represent about emissions and legalities, you should go down you the local courthouse and troll the guys on the 10am docket looking for parking in their V6 Dodge Carvan's running on 4 cylinders.

LOL you know you are in the Forced Induction/Nitrous section right? Most builds you come across in here are going to be up fitted with "illegal" exhaust.

diesel market, however they have started going after gas vehicles now.
I'm quite aware that the majority (98%+) of gross polluters are vehicles that are in an ill state of repair, however you know as well as I do that the government isn't smart enough to know that...

I'm sorry if you feel that way, however I'm not trolling you or your company. CARB and the EPA are monitoring most of the enthusiast forums these days, and are using this for ammo to shut down the aftermarket. Up until recently they have been focusing mostly on the

We do not have emissions testing where Weapon-X resides here in Ohio, so I don't hear much about it. I had no idea that CARB and the EPA were monitoring the forums or really cracking down anywhere other than the usual CA.
