Customer Reviews
Good quality, but shipping was a bit slow.
I ordered some replacement oxygen sensors from Miller CAT last week, hoping to get my car running perfectly again. The quality of the sensors themselves is fantastic, exactly what I needed! They seem really well-made and fit perfectly. My only gripe is that shipping took a little longer than I expected, probably about a week. I was eager to get them installed. Still, their products are solid and I'd recommend them for parts like exhaust gaskets, just be prepared to wait a bit for delivery. Will definitely shop with them again for future needs, maybe even check out their Cat Security options next time!
Consistent quality for my Tacoma
This is my third purchase from Miller CAT. I've bought shields for a couple of my Tacoma trucks now. This time I got the Toyota Tacoma Cat Shield again, and like before, the quality was solid. They always deliver on time, and the parts are exactly as described. It's why I keep coming back, they're reliable. The installation kit had everything needed, just like last time.
Good deal on a security kit
I was looking for a Ford F-150 Cat Shield and compared a few places. Miller CAT had a decent price on their stainless steel shield and it included the security screw kit, which some other sites charged extra for. Felt like I got good value for my money. The shipping cost was fair too. It's a big purchase so finding a good deal was important.
Easy to find what I needed
So, my friend told me about these cat shields, my CR-V is always parked outside. Went to the site, found the Honda CR-V Cat Shield easily. Ordered it. It showed up a few days later, took 5 days to reach Denver. Felt pretty good about the whole thing, less stress now.
Detailed feedback on my order
I placed an order for a Lexus RX Cat Shield last month. The ordering process on their website was smooth, found my model year without any trouble. Shipping took about a week, which was reasonable. When it arrived, the packaging was secure, and all the tamper-proof hardware was included. I opted for the aluminum version and it seemed well-made. Installation was a bit tricky for me personally, but their online guides were helpful. I did call customer service with a question about torque specs, and they were quick to answer and very polite. Overall, the shield feels robust, and I appreciate the theft deterrent window sticker they included. It's a good quality product for peace of mind.
Good shield, fast shipping
Got the Toyota Prius Cat Shield. Shipped quickly. Installation was straightforward. Product felt sturdy. Happy with it.

Thinking of grabbing a shield for my RAV4 during Black Friday. Do they usually have good deals then or is it more like 5-10 bucks off? Trying to decide if I should wait.
planning to get a shield for my wife's CT200h. How long does shipping usually take to say, Portland, Oregon?
Are their shields difficult to install yourself? I'm pretty handy but not a mechanic, wondering if I should just pay someone.
Hey all, just moved to LA and worried about my Prius's cat. Is Miller CAT legit? Like, are these shields actually good or just snake oil?
Does anyone know if Miller CAT ships to California? Some places don't because of emissions stuff, just wanna double check before I get my hopes up for a new converter.
