I've always said that going fully catless vs. a pair of high flow cats is not worth the cons whatsoever. The smell is very strong behind the car, and wafts into the cabin is well. The power gains are minimal and unnoticeable, you'd be better off losing a couple pounds off yourself, lol

Added carcinogens vs. 2-3whp? I know what decision I'd make every time.
