catalytic converter ?

Does anyone know if there is a direct bolt on high flow cat for the first gen ls8. if not who makes a good high flow cat? I'm going to order my magnaflow system for it soon and I might as well do the cats while im under there.

the LS stock cats are high-flow - so no need to swap them unless there is an issue.

I agree

I just did my exhaust today.

No need to mess with anything before the resinators.

thanks guys, the only reason i was asking is that it sounds like i have a small exhaust leak but im not sure where its comming from. I need to put it on a lift with it running and see if i can find it.
