Catalytic converters can be purchased from several places:
* Auto parts stores: Major chains like AutoZone, Advance Auto Parts, NAPA Auto Parts, and O'Reilly Auto Parts carry them. You'll need to provide your vehicle's year, make, and model to ensure you get the correct one.
* Online retailers: Amazon, eBay, and other online retailers sell catalytic converters. Be cautious when buying online and ensure the seller is reputable to avoid counterfeit or substandard parts.
* Dealerships: Your local Cadillac dealership (or the dealership for the make and model of your vehicle) will also sell catalytic converters, but they will generally be the most expensive option.
* Scrap yards/junkyards: You might find a used catalytic converter at a salvage yard, but be aware that used converters might not last as long and could be less efficient. Also, there are regulations around the sale of used catalytic converters, so make sure the seller is complying with local laws.
Important Note: When purchasing a catalytic converter, ensure it's a genuine part or from a reputable manufacturer. Counterfeit parts are often inferior and could damage your vehicle's engine. Always verify the part number matches your vehicle's specifications.
