The Aluminum Prius C Cat Shield™ is one of our best engineering accomplishments. Our unique design and installation process allows you to have a one piece shield that will prevent the bowing or flexing of the shield. By studying the air flow and mounting points of the shield, we were able to increase the stability and rigidity of the shield. Like with all of our shields, you will be getting the most advanced protection device in the market. Fully removable and galvanic corrosion resistant.

Expedited Shipping Info

Customers who need their products right away may want to pay for expedited shipping. Here are a few things to consider when choosing a faster shipping method.

- Miller CAT provides the option for faster shipping but is only a pass through for any charges. We do not make any money off of this service.

- When calculating your possible receive date, please remember that shipping services do not ship on weekends or holidays and that orders received after 1:00pm PST cannot be guaranteed to ship that day.

- Due to COVID and high volume of shipments, carriers are not always able to meet their target shipping times. Please understand we have no control over shipment tracking or times after the product leaves our facilities. 

- If you live in California or the West Coast, you may not need that expedited shipping. UPS ground can reach your destination in one to two days. 

International Purchases

If you wish to make an international purchase please contact us at By default we only ship to a few international destinations. Please be aware that there may be significant fees for you (the buyer) must pay when you receive the product.

Value Added Taxes (VAT) and import duties are some of the fees that your country will impose on your purchase. We do not know what these fees are and they are solely managed and determined by your customs office.

Warranty Information

We have a 90 day manufacturers warranty against defects from the manufacturing process. This covers issues that prevent the proper installation or performance of the product. 

Cosmetic imperfections that occur either from the manufacturing or shipping process are not covered. We do not manufacture a cosmetic product or ones designed for show. Any undercar product will quickly have scratches and scuffs due to the location of the product and proximity to the road. Click here to find out more about the manufacturing process and what you might expect from your product.

We do NOT guarantee our product against theft. Cat Shields are a deterrence device that is meant to discourage theft and/or make it more difficult for thieves to steal your converter. Given the right tools, technique or time, a thief can still take your converter. However, by having a shield, you are significantly increasing your protection against theft. Similar to a car or home alarm, you are making thieves second guess themselves and consider moving onto another target. Deterrence works and we have countless customer accounts and video evidence that converter theft stopped (for those with repeated theft) or thieves looked and moved on to other vehicles. 


There is a 30 day return policy window for unused products. Please visit this link for more information.

*We do ask that customers carefully make their purchases and reduce the possibility of returns as much as possible. Help us reduce the carbon footprint of these shields as they are large and expensive to ship.

2018 Prius C-Miller Cat Shield

Installation will be easy for a muffler shop but, please advise the DIY person that it is an involved process.

Scotty's Muffler in San Bernardino installed my Cat Shield.
Ordering the Cat Shield from Miller and Labor will set you back about $300. but, a way better alternative of having your catalytic converter stolen.

Yes, you can file a claim with your insurance but, having to go thru the process will be a nightmare.

It's a perfect fit, matched to the vehicle.

I love the look of the Cat Shield and highly recommend this product to protect your catalytic converter.

peace of mind, for the moment

The technicians at the Toyota dealership were only able to install 4 of the 6 screws supplied by the kit on my 2019 Prius c. They used some sort of spacer plates to keep the edges of the shield from hitting the underside of the car while I drive. I will monitor the plate over the next few weeks to verify it stays in place. The technicians needed better instructions, please update them.

looks good

Although I understand that cat conv robberies have been rampant on the West Coast, I heard of an occurrence here in the DC area. Being curious, I researched cat converter replacement cost for my make and model; and discovered it is $2200, which is costly, and assuming one can get one quickly if needed. My mechanic assured me he could install a shield. With supply-chain problems and crime seeming to increase, I decided that at least installing a cat shield was very cost-effective at this point, should my Prius become a target for that particular reason. This cat shield and its installation kit arrived promptly, and certainly is strong and durable, not flimsy. I have no doubt it will be tamper-proof once installed.

Buttoned up, good luck bandits!

Good fit, straight-forward instructions, relatively easy install (for an experienced mechanic).

Seems pretty good. Just installed. The included install instructions were a little hard to follow (more detail), had to go online and check out color photos to get the resolution I needed. Hopefully thieves will stay away.
