FAQs
xWill the 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. Toyota's recommendation is 30-60k miles and 60-100k miles depending on your vehicle and driving habits.
Does this 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.

Warranty Information
xWe 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.
Cosmetic imperfections that occur either from the manufacturing or shipping process are not covered. We do not manufacture cosmetic products or ones designed for show. Any undercar product will quickly gain scratches and scuffs due to the location of the product and proximity to the road. Click here to find out more about the manufacturing process and what you might expect from your 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.
