So ive been reading into cats used with a turbo, and find people on both ends of the spectrum. Saying it can be ruined because of the high temps and pressure of a turbo engine, and messing with the turbo (could lead to turbo failing after the cat fails). And other people saying a high flow cat will do just fine.
Just wondering what everyones thought is on it, what are people using in the community? im probably going to just get a testpipe instead as long as my buddy will pass my inspection. Whats the real benefit of cutting the cat out (a tiny bit, alot?)

I have a 3" metallic spun high flow cat in my setup, no complaints and I pass inspection. As far as the difference, couldn't tell ya.

Don't gut your cat out. Leaving the cat housing in will make your exhaust have a spot of bad flow. I'd do a removable pipe for inspections.

and remember you can always flange it and make it removable if you don't want the cat there after inspection.
