ZR1 Cats in Exhaust Manifolds - Max Power?
I wanted to get input on at what power level will the ZR1 cats in the exhaust manifold be damaged or have issues? Has anyone ruined theirs?
I do not have a ZR1, but I have an '12 GS M6 with a PD s/c, at ~ZR1 power (~537rwhp). I know many have ruined their 2.5" LS3 cats with blowers quite easily. I'd like to bump it up a notch (more boost & cam) and realize that I will have to remove them, but wanted to hear the experience others have had.
No cats in my 3" x-pipe (and I have full ZR1 3" exhaust w/ 3" Corsa axle backs). I'm looking to go to ~600-650whp.
Thanks in advance...

Can anyone recommend a good high flow 3" cat for the LS9 engine?
I'm just finishing up a LS9 engine build for my next car and need to make it emissions legal hear in Manitoba.
