The can be hand in hand but dont have to be as well. You can just have your 02 sensor go bad, and the cat would be fine. Just get the downpipe through zzp....my bolt in literally bolted right in, excellent fit and no issues whatsoever. I could not be happier with the DP itself. Get new gaskets if you go this route, it will make things easier to seal up on the install if you are going to do this yourself.

I just got my 3" downpipe with cat from ZZ Performance. I know it was been too long, but my pocket book was slowing up the purchase... Plan to install it this Saturday. Anything special I need to know?
