WARRANTY INFORMATION

Catalytic Converter Warranty

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.

Note: 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. 

Cat Shield Warranty 

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.

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.

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.
