Good product, minor shipping delay

I purchased a Honda CR-V Cat Shield after hearing about local thefts. The shield itself is very well made, feels substantial, and fit my CR-V perfectly. Installation was manageable with basic tools. My order confirmation said 2-3 day shipping, but it actually took 5 days to reach Denver. Not a huge deal, but a small discrepancy. Customer service was helpful when I inquired about the delay, they responded promptly. Prices are competitive for what you get, and knowing my converter is safer provides good peace of mind. Overall, I'm satisfied with the purchase and the protection it offers, just wish shipping was as fast as estimated.

Tacoma shield was a good fit

I ordered a Toyota Tacoma Cat Shield for my 2019 model. The website was pretty straightforward, found my truck and the right product without issues. It shipped out faster than I thought, took about 4 days to reach me in Arizona. Installation was okay, the instructions were clear enough but getting under the truck was a bit of a squeeze. All the tamper-proof hardware was included which was nice. I used their customer support once for a question about torque specs, and they replied to my email within a day. Quality of the shield feels solid, thick aluminum. It seems like it will do the job. My only minor suggestion would be a short video for installation, but overall, a good experience.

Reliable protection as always

This was my third purchase from Millercat Corp, this time for a Lexus RX Cat Shield. I've previously bought for a Prius and a Tundra. Like before, the ordering process was smooth and the shield arrived with all the necessary installation hardware. The quality is consistently high; the aluminum shield is sturdy and well-finished. It's good to know I can rely on them for consistent product quality and a good fit every time. This company is my go-to for converter protection.

Prius shield, totally worth it!

Got the Toyota Prius Cat Shield, stainless steel, and it's awesome! Shipping was quick, like 3 days, and it came with everything needed. Installation was pretty easy, even for me. Now I feel so much safer leaving my car parked. Definitely buying from Millercat Corp again and telling all my friends with Priuses to get one too!

My mechanic said I need a CARB compliant cat for my Lexus RX. Do Miller CAT converters meet that standard for California?

P Phil Silva 1 month ago
Yeah, they definitely have CARB compliant ones, especially for California. Just make sure to select the right option when you're buying.

Not all of them are, but they clearly label the ones that are CARB legal. Just double check the product description.

Hey, I'm in NYC and considering ordering a Cat Shield. How long does shipping usually take to the East Coast?

S Sarah Reyes 2 months ago
Mine got to Florida in about a week and a half, maybe a little less. Not super fast but not terrible.

i think it depends on if they have it in stock. my buddy waited almost two weeks for his CR-V shield to get to Boston, but that was during a big sale.

Are there any active discount codes or promotions going on right now for the Prius Cat Shield? Trying to save a few bucks.

L Lisa Ito 2 months ago
Sometimes they have holiday sales, or sometimes specific model discounts. Check their site, might be something there.

I got 10 bucks off my Tundra shield a while back with a random code I found on a forum. They don't usually stack, though, so pick the best one.

Looking at Miller CAT vs Talons Garage for a Tundra shield. Is there a big difference in quality or installation for either?

W Wendy Vargas 2 months ago
I went with Miller CAT because I liked their security screw system better. Felt more secure than some others I saw.

Heard good things about both, tbh. Miller CAT is really well known for Prius shields, but their Tundra ones are solid too. Probably comes down to price/features you want.

Thinking of getting a cat shield for my Tacoma, but not sure if I should go with aluminum or stainless steel. Anyone have experience with both?

R Renee 2 months ago
I got the stainless for my Prius, felt more robust. A little heavier for sure, but worth it for peace of mind imo.

Aluminum is lighter and cheaper, but stainless steel is definitely tougher against saws. Depends on your area and how paranoid you are lol.

Want to install the Cat Shield myself on my RAV4. Is it complicated or can a regular person with some tools handle it?

J Jared Okafor 2 months ago
It's pretty straightforward if you're comfortable under your car. They send all the hardware you need.

I did my Honda Element shield. Just needed a jack and some basic wrenches. Watch a YouTube video first, there are tons of guides out there.
