I replaced the pre-cats in my 2000. I was getting a cat inefficiency code and decided to replace the pre-cats and O2 sensors at the same time. I used NTK sensors (Which are OE and recommended) and the Walker pre-cats. I don't see a problem with the Walker part. The welds weren't the prettiest in the world, but it was still very sturdy and flows fine. I didn't have any issues bolting them up, the hardest part was getting the old rusty ones off. I didn't feel like shelling out the money for the Magnaflows, and these work just fine. I have almost 30k miles on them now with no issues and passed emissions twice with flying colors.
