Expedited shipping is available for customers who need their products sooner. Please note the following when choosing an expedited shipping method:
- Miller CAT provides the option for expedited shipping, but is only a pass-through for additional charges. We do not make any money off of this service.
- When calculating your possible receive date, keep in mind that shipping services do not ship on weekends or holidays.
- Orders received after 1:00pm PST may not ship until the next business day.
- Due to COVID and the high volume of shipments, carriers are not always able to meet their target shipping times. Please understand that we have no control over shipment tracking or times after the product leaves our facilities.
- If you live in California or on the West Coast, you may not need expedited shipping. UPS ground service can typically reach your destination in 1-2 business days.

Miller CAT will collect the estimated duties and taxes and pay it on behalf of the customer. The final price you see should be the final price you pay.
Returns
We have a 30-day return policy window for unused products. Please visit this link for more information.
Note: We ask that you carefully review vehicle compatibility and other product/install information before making your purchase. Help us reduce the possibility of returns as much as possible and reduce the carbon footprint of our products, as they are large and expensive to ship.
Miller CAT Catalytic Converters are covered by a 5 year/50,000 mile warranty that warrants that a new aftermarket catalytic converter is free from defects in materials or workmanship that would cause the converter to fail an emissions test for a period of five years of 50,000 miles from the date of installation, whichever occurs first.
The warranty is conditioned upon the converter being properly installed on a vehicle which the converter is approved for and that the vehicle was maintained in proper operating condition.
In order to be eligible for a claim, a customer should have proper maintenance records to show that proper diagnosis and maintenance was done to remedy the cause of the failed converter. A warranty claim requires that the defective converter be returned to an authorized dealer, along with the proof of purchase and properly completed warranty certificate. Any incidental and consequential damages are excluded under this warranty, regardless of when the failure occurs.
Our substrates use the same washcoat technology and substrates as the OEM. The converters are made from high-grade stainless steel and formed by advanced CNC spin-forming machines. The matting of the converter improves insulation and thermal stability, eliminating the need for heat shields. Our design minimizes welds on the converter, prevents leaks, and makes it easier to install.
We do our best to update compatibility information as it becomes available. For the most up-to-date information, search for all CARB legal catalytic converters here or the CARB Aftermarket Catalytic Converters Database.
