^^^^You remember correctly
No, I do not have a JoeZ, I am still keeping my modified dual system with my dual glasspack resonators and the stock mufflers. I did, however, discover something interesting while inspecting the head pipes of the stock exhaust. The part just aft of the primary cat where the secondary 02 bung is, is double walled. I will be replacing that section with a single walled 2.5" OD stainless section. I will take picts.

So you are going to install the hi flow cats in front of the secondary bung to hopefully eliminate the possibility of any CEL's. Another advantage you may pick up is that it may pass the CARB sniffer test with the secondary cats. My last Vette with headers and hi-flow cats and with a tune passed, but of course would not pass visual.

I knew PPE did or recommended doing the 02 extension thing on their installations, but really wasn't sure how it worked. The above link seems to make sense and explains it. As I said previously, the other F with the prototype header does not show a cell, and has these 02 extensions.

So you need to have them welded on. This stinks because I really don't want to add stuff to the Joe z exhuast, I already have to cut to add race cats and now I need to weld the o2 bungle. This might hurt the resale of the exhust. Does the sikky headers come pre welded to the headers or are they the same.

No cats belong on race tracks.
