Thanks JFP! After a quick call to the Porsche Dealer, and giving him my VIN, it seems that mt 99' does not have the secondary CATs ( I have not been able to get under it yet) So, the CAT delete is a non-issue. Would the 4-6 bank be drivers side, or passenger side?

I also had a P0420, the Bank 1 cat code and it turned out to be the MAF.
(Accompanied by P01026, P01033)

I sprayed the MAF and the plug/harness contacts with MAF cleaner, then cleared the codes and the code has not come back in a week of daily driving.

I also pulled the air filter and found bits of paper in the filtered side of the airbox, that looked like a part sticker had come apart and somehow ended up on the filtered side down by the water drain hole.

Probably a contributing factor to fouling the MAF.
