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.

Quality product. Straightforward installation.

Exceptional quality of cut sheet metal, parts. Predominantly easy to follow instructions, mounting to existing points. Hardest part for the layperson would be using the included tool to install the included rivet nuts. Would’ve liked the option to upgrade hardware to stainless over zinc. Overall very satisfied with this product and with new peace of mind.

A Matrix is a Corolla

I needed a Cat Shield for a 2006 Matrix and was told it didn't exist. When I told MillerCat that The Toyota Matrix is officially named the Toyota Corolla Matrix, they looked into it and verified that the Corolla and Matrix share the same chassis. In short, I was able to install the Cat Shield 2003-08 Corolla on my 2006 Matrix, and it fit perfectly! Thank you MillerCat.

Great Design and at Least a 10 Fold Savings!

CAT was stolen, dealer had a 6month to 1year back order on parts. Found a local shop that fixed the issue in a single day.

This was installed after the fact, but this would have been at least a 10% investment on what was stolen. Should have installed it before-hand!

Anyone can be a target!

Good to Have Protection

The catalytic converter on my 2006 Toyota Matrix was stolen as it was parked in the street. As I want to keep the car, I looked into shields and found this one on the website. My mechanic installed it, and I now have peace of mind regarding the safety of my car.

Solid

Very solid. And cheaper than the aluminum one, my mechanic was trying to put on. Hopefully it dissuades the next person who tries to take my catalytic converter. Fits well.

Easy to install

I went with the SS option. Quality manufacturing of individual parts. All hardware was supplied. Imstructiond were excellent. I also used the miller CAT instruction video. I work slow so it took me about 2 hours to install including putting the vehicle up on Jack stands and letting it down. Overall a great product and installation is well within DIY capabilities.

Finally a shield for my Corolla!

So glad MillerCAT came out with this shield. While my car is older, I asked them to look into it because I plan on driving this car for as long as I can. Appreciate your help!
