UPDATE (May 2023):
We recommend shields if there is one available for your specific vehicle:
Your best option is to install a Catalytic Converter Shield.
We install two different brands converter shields. The one pictured on the left is a CAT SHIELD manufactured by MILLERCAT. For Toyota Prius models, I believe these stainless steel MILLERCAT shields are a superior product.
MILLERCAT offers this shield in aluminum and 304 stainless steel. The stainless steel version costs $60 more than the aluminum.
CAT SECURITY is another company the offers these shields. I believe CAT SECURITY only offers their shields in aluminum. I actually installed a CAT SECURITY shield on my 2019 Toyota Tacoma after I had my converters stolen in 2022.
This Toyota Prius had it’s catalytic converter stolen recently in Huntington Beach. According to local law enforcement, the theft can take less than 90 seconds. Our customer had us install a theft security device called the CatClamp. Apparently the Prius is a major target for catalytic converter theft locally. In our experience, SUVs and trucks seem to get hit more often because of the easy underbody access.
Common targeted vehicles are: Toyota Prius, Honda Element, Honda Pilot, Toyota Sequoia, Toyota Tacoma
