Cost of catalytic converters replacement.
Dealer said that both cats are bad and gave me a quote of $4,000 to fix both. Is this reasonable?
Always avoid the dealerships for the reason you are asking this question - too expensive. If you are unable or unwilling to perform the work yourself, then locate a reputable repair shop in your area. Always obtain 2-3 written estimates for the same work from different repair shops.
