Pretty easy install and looks great. I highly recommend this cat cage. Seen others but the beefy plates is what sold me. I had my catalytic stolen before and waited 6 weeks to get my truck back. So during the wait I ordered the Miller cat. I hope I never need it again but if I do, it's on there!!!!

Stainless Steel MILLERCAT 2010-2015 Prius Gen 3 Cat Shield™

Had shield installed on my Sequoia last week at Toyota dealer, took them less than 30 minutes. They sent me photos when it was up on lift. Well designed product great fit and finish.

i just had the cat shield installed like 4 hours ago and my catalytic converter is still there, so the cat shield must be doing something right. five stars, all the way.

Install was straight forward and relatively easy if you have the tools for it. I was able to install it in my driver way using a Jack and two jack stands to lift the car.

Well made and a perfect fit. Went together as expected. I used red lock tight on the wing portion. And torque as required, aluminum is easy to over torque. They cover the front cats completely and the front portion of the rear cats. I decded to etch the cats with my info before installing the shield to add further deterrent to any would be thief’s. For 4x4 tundra’s they recommend lifting the transmission to insert the rivet nut. I used a YouTube hack with a bolt that worked just fine and was far better than trying to loosen the transmission and lifting it. The install is easier if you lift the vehicle six to eight inches. Over all a piece of mind and a good investment in my opinion. Also so far no road noise and no heat issues. I wish they offered the option for spare hardware. And the ability to add pictures on the review, it is harder than the install.

We had our catalytic converter stolen from our old Prius. The replacement expense was a great deal. We replaced the converter and immediately got a Millercat shield. So it was clear that when we got our new Prius the first thing we did was buy another Millercat Shield. We now feel very safe leaving our car where it’s possibly vulnerable.

In stainless steel I ordered both the most upgraded (maxx) model and the tamper-proof screws. Installation is complete. We will see over time whether this deters catalytic converter theft, which motivated this purchase.

Great product however I'm with everyone else. I wish it covered the rear Cats. Other than that it's great quality and serves a great purpose thus far!

Quick, easy and fast installation, an hour or less.

A Toyota Dealership Service Department installed mine. No need to go to an outside or independent muffler or tire shop. I'm glad Toyota dealership sold the stainless steel cat shield...more strength. Besides, my insurance adjuster advised me to get one too. MILLERCAT's Sam Lee answered my questions about the product and was very accommodating. Would recommend more Prius owners to get one.

Nice product, thick aluminum, great security screws and easy install. Would love for y’all develop something that covers those rear catalytics all the way. Perhaps a guard for the Transfer case?

Couldn’t get one for my older gen at the dealer so I appreciate I could find it here. Came fast !

The shield is fantastic! I took my Prius to a muffler shop for the install. The crew said the directions were easy to follow, it only took them 30 minutes to install. (In fact, they stated it was much easier than other brands they’ve previously installed.)

I highly suggest NOT taking your car to the Toyota dealership for the install. Yes, I realize they are considered “certified” installers but when I called the Toyota dealership for a price quote- they stated it would cost $385!! When I asked why it would be so high (knowing from these comments that the average install time is 30 minutes, w/ the proper tools and lift) they claimed it would take them 2.5 hours to install! So no, I do not suggest taking your car to the dealership. They will rip you off. There are plenty of reputable companies/businesses that can assist. Just call and ask if they have experience installing catalytic shields. Easy.

Since the install, I worry much less about leaving my car unattended. Most thieves will see the stainless steel shield, and will move onto the next car. It’s too time consuming and can be too loud for them to attempt to saw it off your car without drawing attention to themselves.
I’ve had no issues with rattling or any noise.

as a prior aircraft interiors installer we used 2 face tape to hold things in place like the small and large spacers, also I found out its easer to install 4 bolts and ( spacers ) first then the rest next , 1 item I'm not happy with both special anti tamper only lasted tell last bolt was installed and i was carefully installing them .
