Since my cat is blown anyway, what goes into gutting the cats? Am I still gonna get that sulfur smell? Also has anyone ever been failed for emissions for doing it? Thanks.

Also what gains/benefits will I get from doing it?

 

Blown cats on a year old car? How do you know that? If they have failed, GM should replace them for free, I think...

As far as I understand, gitting a cat means you leave them where they are and just stick a pipe straight through them. Another thing what can be done is to just try to get all the stuff out of there.

That'll get you through visual inspection. Not sure if you'll pass the sniffer, though...

You'll proabaly get some hp gain by doing that. Probably not much, though... I'm sure somebody will throw in some dyno numbers.

If you want to do something with your cats, I'd suggest installing a pair of high flow cats. That way you don't at least have to worry about the emissions.

Later!

You'll need the O2 simulators. Just get some highflow cats, it's a measly 2hp for a cleaner environment.

There is a warranty for 8 yrs 80k miles on the cats. They have to replace them if they are faulty.
