Prius Gen 1 and Gen 2 owners are highly recommended to change their rubber exhaust hangers when installing a Cat Shield™. After years of wear and tear, your hangers should be replaced to eliminate any potential rattling of the exhaust with the installed shield.
The hangers are sold as a pair (2 hangers) and are quick and easy to install. If you had your converter replaced recently, your installer may have added new hangers and you may not need these.
Will my Cat 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.
Does the Cat 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.
Free shipping is available to the lower 48 States. Please note that we cannot deliver to P.O. Boxes. Orders will take 1-2 business days to fulfill.

We have a 90-day manufacturer's warranty against defects from the manufacturing process. This covers issues that prevent the proper installation or performance of the product.

We do NOT guarantee our product against theft. Cat Shields are a deterrence device that are meant to discourage theft and/or make it more difficult for thieves to steal your converter. Given the right tools, technique or time, a thief can still take your converter. However, by having a shield, you are significantly increasing your protection against converter theft. Similar to a car or home alarm, you are making thieves second-guess themselves and consider moving onto another target. Deterrence works and we have countless customer accounts and video evidence of derailed converter theft.
Very serious site and fast shipping
No problems encountered so far
Hoping that there is no overheating on long journeys
On my 2006 Prius had a V2 Cat protection plate was installed, ever since we used to get the plate vibration noise and found that exhaust pipe was touching the plate and causing weird noise. After installing New Exhaust Hangers plate vibration and noise completely gone. Good product and works as expected.
These appear to be as good equality as OEM. Easy to replace with a little WD-40 to help slide them on.
My mechanic said everything was really great.
Had to make a re-adjustment because the plate flexes and is very loud. Adjusted as best we could and it’s still a bit loud especially if the road is rough. Also, there are four long stud’s across the mid section of the large plate but I could only use two as there are bolts sticking out of the threads that the bolt holes line up with. Looks like an excellent deterrent but at the expense of it sounding like I have a box of pots and pans under my car getting shaken and rattled.
