6th Gen ('00-'05): Should I get a ZZP Downpipe?
#23
2.5" is fine if your not planning on modding very much. 3" would support more mods for more hp but without doing the mods it allows you will feel a little loss in low end.
To answer your question about the rear o2. Once the code is deleted the sensor is turned off so whether it's there or not it doesn't matter. They make o2 bung plugs to plug the o2 bung if you decide not to install the rear o2.

If you're going with the 2.5" downpipe I would do a little shopping around before dropping your coin on the ZZP. There are several replacement downpipes on the market (Magnaflow/Walker/AP) that flow as good (or better) then the ZZP downpipe. Save yourself some money. The only thing you 'gain' on a non-modded car with the ZZP downpipe is bragging rights that you have a 'ZZP' downpipe. The gain from removing the u-bend will be minimal.
