The Gen 2 Cat Shield ™ offers the most protection out of any product in the market. The bottom lip deters thieves from cutting the rear pipe. Louver vents provide efficient cooling, visibility for smog techs to read the converter part number, and protects the vehicle from debris. Fully removable, galvanic corrosion resistant, and no large openings for thieves to cut through. We highly recommend pairing this shield with our Deadbolt.

MillerCat Peace of Mind

I had mine installed at a body shop. Installing was fast. Now my mind is at ease. I put the sticker in front of the driver’s side, I just wished it was the clear one but then it’ll be less visible. Ii had my Catalytic Converter stolen twice and reported them to LAPD and nothing, not even a patrol in my area. Now I can sleep better.

Very Nice But Could Use Some Improvements

I purchased the aluminum shield and a pair of exhaust hangers. Even with the new exhaust hangers, the converter is hitting the shield especially when accelerating from a standstill. I ended up placing some spacers to solve the problem. If the shield was molded with a valley to clear the catalytic converter.
that would solve the rattling. Also, the shield needs to be about 5 to 6 inches longer in back because you can still get a reciprocating blade to cut the back end.

so far so good

The whole process took way longer than it should have BUT that was due to the pandemic and UPS who do not guarantee their 3 day shipping by the way! The fact that it had to go across the country didn't help, but MillerCAT was helpful and the shield did eventually mechanic couldn't order the necessary bit to install it so had to find someone else to install it, cost $110. Otherwise it's good! Who knew a 2007 prius had anything worth anything in 2021? Wish I knew sooner. Glad this product is available!

Feeling much better now that my Cat Shield is installed!

Easy installation with the proper tools. Feeling much better now knowing that the bad guys will have a much harder time getting to my catalytic converter.
