What do/did y'all do with your post-cat O2 sensors when you converted your Boxsters into SPBs? Did you just remove them? Tie them up out of the way? Or, did you do like whoever made the homemade-looking exhaust on my car and weld 4 bungs into the pipes and stick all of the O2 sensors in the exhaust?

The reason I ask is the new Soul SPB exhaust only has two bungs for the pre-cat O2 sensors (same as the Fabspeed SPB exhaust). I'd love to remove the post-cat sensors from my car and save that pound or so. But, I don't want to create an engine fault/code.

Thanks!

Edit -- to clarify, my exhaust doesn't have any cats, just straight pipes. Since I'm not getting any engine faults now, it seems like the post-cat O2 sensors aren't really doing anything. Can I get away with removing them, or do I leave them in and just tie them up out of the way to prevent getting an O2 heater fault, which I've gotten on other cars when the sensor was failing.

I tied mine up on to the top of the aluminum heat shields. My car is still street legal and only throws a code 2-3 times a summer, usually during long drives out to the Glen. A simple and quick clear with my bluetooth OBD reader/app and it's gone for a month or so.

Mine has the sensors removed and the leads tied together. The ECU only cares that the value is different then the fronts.

Zip tied up is easiest

I removed mine

I removed mine and removed the bulb for the CEL from the pod.

I tied mine out of the way, and (almost?) never get a CEL.
(I didn't remove the CEL bulb like Doug did, but I did remove all extraneous bulbs such as the airbag warning light.)
