* Auto parts stores: National chains like AutoZone, Advance Auto Parts, NAPA Auto Parts, and O'Reilly Auto Parts will likely have them in stock or be able to order them. You'll need to provide your vehicle's VIN or engine details for a proper fit.
* Online retailers: Sites like Amazon, eBay, and RockAuto sell catalytic converters. Again, accurate vehicle information is crucial for selecting the correct part. Be wary of extremely cheap options, as quality can vary significantly.
* Specialty exhaust shops: These shops often deal with catalytic converter replacements and may have used or remanufactured converters available. They can also handle the installation.
* Junkyards/salvage yards: You might find a used converter here, but it's important to ensure it's in good working order and meets emissions standards.
Important Considerations:
* Emissions compliance: Make sure the converter you purchase meets your area's emissions regulations. Using a non-compliant converter can result in fines.
* Exact fit: Providing the correct year, make, model, and engine details is crucial to getting the right part. The VIN is the best way to ensure accuracy.
* Cost: Prices vary greatly depending on the brand, type (direct-fit vs. universal), and whether it's new, remanufactured, or used.
* Installation: Replacing a catalytic converter can be challenging. Unless you have experience with auto repair, it's best to have a qualified mechanic install it.
Before purchasing, always double-check the part number and specifications to ensure it's compatible with your 1990 Cadillac.
