If your goal is to gain power you're wasting your time. I gutted the cats on my old 2000 WS6. I used to make 475 rwhp with nitrous through a cutout and stock manifolds and cats. When I gutted the cats, I took it back to the dyno. Result? 475 rwhp...same bottle pressure...same conditions. The cats aren't the choke point of the exhaust...it's the manifolds.
Now if you want to gut them for sound (which I think sounds like ***), then go ahead and do it. Just be prepared to buy O2 simulators for the rear sensors or have it tuned out. You will throw an SES light.
