I've got an issue that will require me to replace the driver side cat on my 03.5 sedan, and I'll be looking to go the used part route. I am wondering what model years all use the same part numbers - I figure 03-06 and possibly 07 too. Does anyone know the part numbers and can verify the same part used on multiple model years?

Toward that end - if anyone has stock cats from a sedan LOW MILEAGE they would like to sell, PM me. Thanks.
