Last weekend installed the Cat shield in stainless version. Perfect measurements and fit to my 2021 Prius Prime like an OEM part. I opted for the upgraded security screws and the hardware was 1st class Heavy duty, "nice bolts" My only gripe is a desire for extreme protection with 4 security head bolts instead of 2 as provided. But the extra 2 security bolts required extra effort to get access to install, so it was nice Miller send the extra 2 on my request as I like securing all 4 corners with theses awesome security head bolts. Beware trying to get the extra 2 bolts ( total of 4) will require extra install time. 5 star produce and company
I installed the Cat Shield on my 2019 Prius Prime using drive on low profile Rhino Ramps. The secret to easy installation with limited vertical access is to clean the shield with alcohol and Super Glue the spacers to the Cat Shield the day before installation.. Dollar Tree sells a 5 pack of single use super glue for $1. When super glued the spacers hold the reinforcement brace in place for easy install. The spacers are slightly smaller than the holes in the shield so I flipped the shield over to visually center them before super glueing them in place. Install the rubber dampers first so you remember which side the spacers go on. No more fumbling trying to center and hold the spacers, brace, and shield in place while trying to install the bolts.
This is my 2nd Prius and highly concerned with the increased number of catalytic converter thefts. Decided to invest in my anxiety and buy the MillerCat in the thicker stainless steel. Quality is exceptional, no sharp ends, well cut and holes perfectly aligned where they should be. Hardware was of good quality. I used the YouTube videos to help with installation, the included pictures weren't enough.
Compared to the competition, I didn't need any special tools to buy or holes to drill into my car. Took about 2 hours with my son and now I can sleep better at night. Money well spent, easy to install and plenty of peace of mind.
I purchased the Miller Cat-shield for my 2020 Prius LE and went to a shop recommended by the local Toyota Dealership Service Advisor. Costs me another $150 for the installation. It only took the technician a mere 15 minutes. I now can park outside my house and no worry. Thanks MillerCat Corp.
