In the Detroit area, we have several foreign auto parts stores. THey get their parts from the actual suppliers to Toyota. May be the best to just shop for prices at Toyota dealers on the internet. You can save money on tax, usually. Is car in good shape??? if it is, then use new Toyota converter, but only AFTER you have tuned the car properly. Otherwise, you can stress out the new part. Most converters fail from having higher polluting engines due to lack of tune-ups.
