I like it, but I don't know that I'd keep it. Piss em off and all they have to do is reach over about a foot to the passenger side and cut the HV cables. or key the car as they leave..or kick in a panel. It's not like they're unwilling to damage your car just for the heck of it. Easier to just stick a bumper sticker on it that says aftermarket catalytic converter installed.
