What o2 spacer are you using??
I'm throwing some post o2 codes after an install of a high flow cat.
I tossed in some spacers that worked on my 993 with a cat bypass and no luck.
What are you using if you have a cat-bypass ? Or are you just having the ecu recoded?

I have installed these and they work fine. http://www.bigdaddiesgarage.com/mini-cat-cel-fix.html?
