I decided to put on a Cat. Shied with all the Prius Cat. thefts going on here now. Very straightforward install. Oh be the way it's the Steel one.
What do the tamper proof screw heads look like? What's needed to remove them? Maybe fill in their sockets with some two-part epoxy?
How long did the install take? The peace of mind from having one would be pretty good. On the other hand, while this type of theft is interesting thus newsworthy, given the millions of Prius cars in the country, the odds must be pretty low of actually being a target. I also worry about noise issues that people have reported. While the instructions mention rubber dampeners, I wonder how long they will hold up, given the environment in which they are used.
They would haft to use a Grinder and grind them down or a cutting wheel to slot them so they could use a flat head to back the screws out. Which would take them too much time to do, Time is a big factor to those P.O.S.
Really not long at all, Using the nut tool took longer than anything else, that tool thing is a Bitch to squeeze. No noise, comes with Rubber Bumpers.
