I FEEL SAFTER NOW

We had our catalytic converter stolen from our old Prius. The replacement expense was a great deal. We replaced the converter and immediately got a Millercat shield. So it was clear that when we got our new Prius the first thing we did was buy another Millercat Shield. We now feel very safe leaving our car where it’s possibly vulnerable.

Great - fit perfectly, and took around 1 hour to complete installation.

Instructions were clear, easy to follow. Installation was fairly easy - 4 bolts and 2 fasteners out, and 6 bolts with spacers back in. No cutting or drilling - everything can be removed and reverted 100% back to stock if I wanted to. Fit is snug and tight, quality great - recommend!!

Fits great.

Product is great overall. I would rate this less stars only for the installation instructions. As someone else commented... I wish they would put stickers on the plate... This side down...Front/Rear. Installed the wrong way at first and had to take down and reinstall. Also paid extra for the security bolts. Not sure why its only 2 bolts. Why not all 6? Instructions were not clear for my specific model. Neither the youtube video or the pdf instructions online were the same as my 2021 Prius Prime. Its not exactly rocket science to install but it took extra time trying to figure it out. Once installed it did fit perfect. Seems solid as a deterrent. Highly recommend.
