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.

do you know the make of yours?

These are the highest flowing

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