The RnD in cats these days means you can run them with no issues, if you get a decent one. EG: What the ERD cars have.
You sacrifice a certain type of exhaust note, but the lack of tolerance towards no cats is almost not worth it.
I’m a fencer sitter, when you start making big power, one would think the un burnt fuel and heat would kill them pretty quickly?? But I guess they just become a part of the maintenance you need to keep on top of with a more serious car.
