It's still going to sound good but just a little quieter.

That's not a correct statement....it depends what cats you have.

I'm running ProFlo cats w/ my DynaTech SuperMaXX LT's. Even w/ the turbo cam still in the car it sounds excellent. Should sound great when I get the new cam in

Aftermarket high flow cats will reduce rasp and reduce the volume some. Which in my case is good....as the GMMG exhaust I have is still loud as F@ck at WOT on the current H/C setup. It would probably be too much if I had an ORY.

I think ARH uses the Magnaflow Hi Flow metallic core cats and mine is loud above 3500. I actually wish it was quieter so I could be a sleeper but it is hard to make a H/C full exhaust LS1 quiet by most standards without choking it

I have a 233/239 112 cam in my GTO. The video here is of the initial startup with cats and stock mufflers. It has terrible video because it's dark but the sound is what you're wanting anyways.

It sounds much better without the cats.
