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.

Modern Day Must Have

In this day and age you have to take protection seriously. This product fits the bill. I chose the aluminum version instead of the stainless steel. I’m trying to be weight conscious since I’m trying preserve payload. At first I thought I gave up security/durability by going aluminum but let’s be honest, this is about deterrence. Could they cut this, of course but these folks are working a time, so this will slow them down… they will move on to an easier pick.

2022 F150 Cat shield

Solid fit & peace of mind

product arrived quickly, fit like a gem and installed in about 30 minutes. Great insurance policy.

Absolutely fantastic product

Well made, well thought out. Should do a great job protecting my 2025 F 150. Also doesn’t impede changing oil or possibly checking the transmission fluid level. Highest recommendation.

Good looking product

Looks great and easy to install. Rear of plate does not sit flush with rear factory skid plate, no biggie though. Just loosen the factory rear plate and bolt up the Miller cat one then tighten the rear factory one down overlapping it.

Speedy Delivery and Great Product with a Minor Drawback

The Cat Shield arrived earlier than expected, and the quality appears excellent. The instructions were clear and easy to follow. The installation wasn’t very difficult, yet I expect removal would be very cumbersome for a thief. The coverage also seems adequate. The only downside is that I will probably need to remove and reinstall it each time I have my transmission serviced.

Secure, strong & easy to install

Too bad these shields are needed. But, they are. This stainless steel Cat Shield feels very rugged, strong and heavy. It comes with security bolts, so don’t lose the included bit/driver.

Ours had one of the pressed-on captive nuts come loose and Miller Cat quickly offered to replace it for free. Fast and solid service. This shield is so rugged, that I wonder if it will function as skid plate. Not that I am planning for it to make contact with any rocks or terrain. But, on our 2025 F-150 the transmission pan is plastic and seems very exposed. It now feels properly protected and the Cat Shield looks liek it can handle any abuse.

Best option that I've seen

This was the 3rd cat guard that I bought. The first 2 (different brands) wouldn't work. This one has the largest opening for oil drain access and was easy to install. Took about 90 mins from jacking up the truck to putting the tools away. Should deter any dirtbag cat thieves

excellent material

Great material (stainless), but why couldn't it have been made in one piece?

Future Improvements

The installation was straight forward but there was difficulty to fit with the 2024 F150 back shield behind the transmission circumber as it overlaps with back driver side fitment of your CAT shield and also the L shape brackets could be made continuous metal rather than a gap in the middle which could be a weak point.

Overall, a decent product

The shield will serve as a good, symbolic barrier against all but the most determined thieves. It would be better if it were made from steel. Yes, I know they had that option for an additional charge, which doesn't make sense since aluminum is more expensive that steel.

The installation was easy and straight forward, but be careful with the extremely sharp edges of the aluminum shield. They should invest a few dollars in deburring the edges.

Lastly, their shipping was fast and it was well packed.

Nicely made, fast shipping, fit well.

For a 2023 F150 4x4. I had it installed by a local muffler shop, although the instructions were very well written. Took them about 45 minutes. All parts included.

Perfect fit and excellent quality

I purchased the stainless steel version and installed it myself. I followed the instructions and completed installation in a short amount of time in my garage. Everything fit perfectly on my 2023 F150 FX4. For access to work under the truck, I raised it 3 inches by driving the front tires up onto a couple of 2" x 10" boards.
