I'll get an anti-fouler, but I see no reason to punch the cat out. I'd rather have a 94% functioning catalytic converter than none at all. I didn't mention, but there's noticeably less restriction after washing it, and it might be my imagination, but my butt dyno tells me I'm getting more at the top of the rev range.
