The estimated cost to update the catalytic converter on a 1989 Cadillac Fleetwood with a 305 Oldsmobile engine typically ranges from $200 to $1,000, depending on factors like the specific parts needed, labor costs, and whether you're opting for OEM or aftermarket parts. Additionally, older vehicles may require custom work, which can increase costs. It's advisable to get quotes from multiple mechanics to find the best deal.
