Customers who need their products right away may want to pay for expedited shipping. Here are a few things to consider when choosing a faster shipping method.

– Miller CAT provides the option for faster shipping but is only a pass through for any charges. We do not make any money off of this service.

– When calculating your possible receive date, please remember that shipping services do not ship on weekends or holidays and that orders received after 1:00pm PST cannot be guaranteed to ship that day.

– Due to COVID and high volume of shipments, carriers are not always able to meet their target shipping times. Please understand we have no control over shipment tracking or times after the product leaves our facilities. 

– If you live in California or the West Coast, you may not need that expedited shipping. UPS ground can reach your destination in one to two days.

If you wish to make an international purchase please contact us at info@millercat.com. By default we only ship to a few international destinations. Please be aware that there may be significant fees for you (the buyer) must pay when you receive the product.

Value Added Taxes (VAT) and import duties are some of the fees that your country will impose on your purchase. We do not know what these fees are and they are solely managed and determined by your customs office.

We have a 90 day manufacturers 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 a cosmetic product or ones designed for show. Any undercar product will quickly have 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 is 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 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 that converter theft stopped (for those with repeated theft) or thieves looked and moved on to other vehicles.

There is a 30 day return policy window for unused products. Please visit this link for more information.

*We do ask that customers carefully make their purchases and reduce the possibility of returns as much as possible. Help us reduce the carbon footprint of these shields as they are large and expensive to ship.

If your Lexus, Toyota, or Suburu has one of the following, it is likely you have a vulnerable headlight control module and a CAN Bus Anti-Theft Shield may be needed. Please see the fitment chart at the bottom of this section for the most up-to-date information.

  • Adaptive Front Lighting System (AFS)
  • Triple Beam Headlights
  • Auto-leveling (2017+ models)

If you are uncertain about having AFS or auto-leveling, please do the following:

  • Check your window sticker when you purchase the vehicle to see if your vehicle was equipped with AFS or auto-leveling.
  • If your headlights adjust in the direction of your steering when driving at night, you likely have the AFS system.
  • If your headlights move up and down when you start it at night, you likely have auto-leveling headlights.
  • Open the hood of your vehicle and locate the headlight computer control module, usually attached to the headlight. The exact placement may vary depending on the vehicle model. The shape of the module is unique and should be easy to confirm.

Vehicles in Europe and Canada may be at higher risk due to the earlier and more widespread adoption of the adaptive style headlights that require a computer control module.

WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, visit P65Warnings.ca.gov.

Can Bus

This is a very important add on. The installation was not bad at all. Remove the top portion of the front bumper, you will have to removed parts of the side molding and the remove head light assembly. Then install the brackets and reverse the process.
