Cat's will not effect the dc service contract but according to federal law, the factory cats can only be replaced using factory converter during the federal 8/80 emissions warranty/fines can be ridiculous $50kAs a new owner of a stock Viper, i would like to install HF cats and a new cat-back exhaust. Can anyone tell me if this will in anyway void my DC extended warranty?
Thanks,
