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.

New version catshield for 2021 Highlander Hybrid

Millercat has been out goto for catshield installations. We ordered the latest version online, but we received a called from Millercat saying a newer version will be available within a week. We decided to wait the week and when the part showed up in less than 1.5 weeks, we were surprised. The parts were quality and thick unlike other brands. Easy for installation. Highly recommended.

2023 highlander hybrid install

Installation went well. Instructions were well written, you do have to study them for a while to have it all make sense. Doing a dry run by assembling separate from the car just to get a feel how the pieces fit works well.
