CAT SHIELD — WARRANTY INFORMATION

90-day manufacturer's warranty

Cat Shields carry a 90-day warranty against defects that prevent proper installation or function. Warranty requires proof of purchase from an authorized retailer (millercat.com or Amazon).

What's not covered

  • Surface appearance — please read before purchasing. Cat Shields are raw stainless steel and aluminum components. They are not painted, powder coated, or finished. Mill marks, minor scratches, surface oxidation, and manufacturing residue are inherent characteristics of these materials and are present on every unit we ship. This is expected and normal. Products that show these characteristics are not defective and are not eligible for a return or warranty claim.
  • Damage from improper installation, road debris, or modification
  • Labor, diagnostics, or incidental costs

Theft deterrence

Cat Shields are a deterrence device designed to significantly increase the difficulty of converter theft — not to make it impossible. Given enough time and tools, a determined thief may still succeed. We have extensive customer accounts and video evidence of derailed theft attempts.

For warranty claims, email support@millercat.com with your order number, proof of purchase, photos, and a description of the issue. View full warranty information.

Please check compatibility below prior to purchase. Shield may have some surface imperfections. Professional installation recommended. Package includes catalytic converter shield, tamper-proof hardware kit, Cat Shield Protected sticker, and detailed installation guide. Order today to protect your vehicle from catalytic converter theft.

Will the shield interfere with maintenance such as engine oil and transmission fluid changes?

All Miller CAT Cat Shields will not interfere with your oil changes. Some vehicles will require the shield to be removed for transmission fluid changes. Check your maintenance schedule on how frequently to change your transmission fluid. For Toyota vehicles, Toyota's recommendation is 30-60k miles and 60-100k miles depending on your vehicle and driving habits.

Does this shield cause the converter to overheat?

No, our shields will not cause overheating or damage to your vehicle. In addition to shields, we manufacture catalytic converters, so we know how to protect them without damaging the converter or your vehicle. Read about this in more detail.

How long does it take to ship?

We know you can’t wait long to protect your converters when theft is so rampant. Here at Miller CAT, our shields are made to stock and ready to ship. Unlike many other companies that make shields to order, we fulfill orders in 1-2 business days and if possible, on the same day.

FITMENT TABLE

Our Fitment Guarantee: While we do our best to test and verify every model, it is impossible to know for sure. We guarantee that if your vehicle is listed on the fitment table and you purchased the right shield for your vehicle but the shield does not fit, we will issue a full refund including return shipping on the product. The vehicle must have the original converter and no modifications to the suspension. If you are unsure about your fitment, please send photos to support@millercat.com to verify fitment before purchase.

2026 Prius plug in hybrid

Love that Amazon prime was an option to getting this super fast placed my order on Thursday had it at my door by sat afternoon. Super easy to install with great step by step instructions. Took me longer to lift the car off the ground longer then to install the part itself that’s how easy it is to install. With basic hand tools. Love that it comes with security locks hardware. Worth every penny and looks good also . I went with the stainless steel option to help the longevity from rusting in the future. #Millercat

Excellent product

The Millercat shield is an excellent and well engineered product. I purchased one for my 2026 Prius Limited AWD and installed it myself. It required no drilling holes and uses existing manufacturer screw holes. I love the locking bolts that have their own key locks. I highly recommend this product. I am going to purchase one for 2015 F150 truck.

Don’t think if it actually works to prevent stealing, but at least some resistance for them, and it looks kind of cool.

Good cat shield but could be better

Cat shield was easy to install and seem to protect catalytic converter but it leaves the after converter exposed. So my neighbor also has cat shield and thieves end up cutting the after converter. Miller should make an extra piece to cover that too

Perfect fit protection

The shield and intructions to install it were perfect; the only thing I noticed is that the provided bolts are too soft and the torx cavity too shallow.

Hoping the Cat keeps her “intact!”

We lost the Catalytic converter to our ‘06 Prius, and we’re hoping the Cat keeps our 2026 version unharmed!

'26 LE - great fit w/SS shield (yes those 4 x brace bolts are *!<^#! to re-install)

Fast shipping, well protected in cardboard box (no shipping damage dents/dings/creases). DIY install (not on lift), 1st front wheels on 17 deg. ramp, 2nd chock rear wheels & floor jack @ front center lift point, 3rd jack stands at front pinch weld points. I'm old (70's), tall, and big (~235#), needed the jack stands almost full extension to squeeze around, but got the job done. Instructions are good (although as a reminder could have mentioned 'remember to re-install the 10mm floor pan splash shield plastic nuts' - I almost forgot). I wasn't able to use a torque wrench with the M8 security bit on the 2 x supplied M8 security brace bolts (not enough clearance) but confident I torqued them 'adequately'. Appreciated having the small tube of thread-locker supplied as part of hardware package. One minor complaint - wish MillerCat would have supplied 2 x Cat Shield stickers (instead of just 1) - I wanted to place stickers under the car (one each side on the plastic underbody covers), so the stickers will be visible to any thief looking under the car or attempting to jack the car from the sides. But can't do that with only 1 sticker.

I’m somewhat handy and I was able to install it myself. The shield feels strong and I have piece of mind that my car is protected.

Catalytic converter shield for 2024 Prius

I ordered online. It shipped to my house in 3 days. Arrived in perfect shape. I took it to my local Muffler Shop and it was a perfect fit. It looks good underneath my car and I can sleep better at night knowing my catalytic converter is protected. Very satisfied and would highly recommend.

Reasonable price, well made, easy installation

MillerCat is the source for the dealer installed shields from Toyota (at least at my dealer) but their prices direct are better (unsuprisingly) and installation (with a little help from YouTube) was pretty simple and saved another chunk of money the dealer would have charged. I opted for the stainless version (rather than the aluminum one). Definitely worth it if you're in an area where converter thefts are a thing.

I don’t know what you want me to say but to describe it. It looked solidly built, recommended by a Toyota mechanic so it must be good. Your company though sent me the wrong size bolt. The mix up was handled professionally, communication was great and the right bolts are supposedly on the way. No CC is safe and I know that for a fact but looking at your Cat Shield, they are going to work for it to steal my CC. Thanks

Perfect fit

Clear instructions, easy to install. The sheet metal is thin but hopefully enough to discourage potential thieves.

Perfect Fit! Great Quality! Easy installation!

This stainless steel Miller Cat Shield fit perfectly on my Toyota Prius Prime 2024. Instructions were very clear, and easy. I figured with a proper car lift, it shouldn't take more than 30 minutes, so I went to my regular garage.
My mechanic (whom has experience installing other brand of catalytic converter shield on different vehicules) even told me he was impressed with the quality, fit, and ease of installation of this Miller Cat Shield on this car. No drilling required at all. Took him a bit less than 30 minutes to do the installation.No issue so far (1 week since installation).
Note: Packaging did not have adequat padding for such a thin hard metal item. (Box probably too small to add more/better padding) and the shield tabs had sliced through the box edges in some places. But luckily there was no damage to the shield! So in the end all good. Super happy with purchase!

Piece of mind

I chose the aluminum thinking that the goal is to discourage any catalytic converter thief.
I hope my rational is sound.
