Finding an actual direct fit is not as easy anymore. Walker probably still does it and Magnaflow might but other than them probably only universal options are available.

You can check Rock Auto. I bought direct fit cats with the factory flat spot and solid y-pipe through them for my 2000. Made by Walker.
