I have gutted cats and they sound great the only problem I have now is that I have a horrible exhaust leak from where the cat meets the header. I think its the hardware I used. Can anybody tell me where to get some new hardware and gaskets? Thanks I have tried to thighten them up 3 times already but they keep coming loose.

I ran the same set of O2 sims for 4 years and never had one burn out. Guess I got a really good set then.

Unless you can find someone to tune them out for free, it's just not worth paying for a custom tune just to delete the rear O2s.....

However, reading below:

....maybe Fastchips already tuned out your rear O2s making this a non-issue?

Not sure if he tuned out the rear 02s or not but I didnt gut them till after he tuned my car. Was 450.00 took about 1 min and said he added 39 horse. But if he does have the capability to tune them out maybe he will hook me up with that..

I turned my cat out, and decided on going back with just a same o.d. length of pipe. Simple solution to the open compression gaps that can happen welding it back in place. Makes for a harder rump also

Oh and you might find a place that buys cats for cash, check your local scrapers. That palladium is recoverable.
