Do not install catalytic shields on Prius V

Use another vendor or buy a quality CAT shield. Mine isn't a Miller CAT shield; just a no-name brand - It doesn't even come close to touching or scraping. I go over speed bumps all day long without issues. Bend the shield a bit and/or place some spacers between the frame and shield to avoid this. As long as a CAT thief see a shield there; they're less likely to go after your car.

Just my humble opinion......

 

I had a Toyota dealership install mine, was a reasonable price. No problems since then and that was many thousands of miles and a few years ago, around the time I got it lifted.

 

An old Bronco II that I had came with a skid plate protecting the transfer case, and it mounted with two bolts to each frame rail, four bolts total.

The bolt holes made a perfect rectangle, so naturally, a transmission shop that worked on it once discovered they could put the skid plate back on yawed 180°.

In that position, the catalytic converter would touch it every time I accelerated (longitudinal engine, exhaust on the right, + torque = exhaust pressed down against the plate).

I did notice some buzzes but didn't investigate right away. About a year later the catalytic converter broke off.

 

Quality control should have stuff like that on their check list; say pull one of the bolts in a bit, so it can only go on one way, can’t be reversed, flipped, whatever.
