Customer Reviews
Reliable for my Honda
This was my third order from Miller CAT. I first bought a Cat Shield for my Honda CR-V a couple years ago, and that went smoothly. This time, I needed a replacement oxygen sensor. The part arrived quickly, within 3 days, and was exactly what I expected. Their products have always been consistent for me. I keep coming back because I know I'll get the right parts without any hassle, and the quality holds up.
Good value for a Prius shield
I was looking for a Toyota Prius Cat Shield and found Miller CAT. I checked a few other places, but their price was competitive even before I found a discount code. It took about 4 days to reach me in California. Installation wasn't too bad, just followed the video instructions. For the peace of mind, it was definitely worth the purchase. Felt like I got a solid deal on it.
Quick shipping, solid product
Ordered a Toyota Tundra Cat Shield. It shipped fast. Packaging was good. Installation kit was all there. Good fit. Happy with the purchase.

Hey, wondering about the install process for these cat shields. Do they come with all the screws and bits, or do I need to grab extra hardware?
I saw something about a discount code for Prius shields a while back. Are there any active ones for Prius owners right now?
Does Miller CAT ship to California? Need a CARB compliant converter for my old Civic.
How long does shipping usually take? I'm in LA and need a shield for my Tacoma pretty soon.
Are these cat shields really legit? Like, do they actually stop thieves or just slow them down?
