Makes no sense to me. You removed the cats but kept the O2 sensors and they are not Porsche sensors?
Sensor nearest the engine signals the ECU and works together with the MAF to adjust the air fuel mixture. O2 sensor nearest the muffler checks the quality of the job the Cat is doing and merely reports when the exhaust stream is not cleaned up enough.
You are making mods before the basics are working.
Did the car give codes before you did any exhaust work on it?

Dllrd23 thanks for the reply no we have not replaced anything that replicates the o2 signal if i remember correctly we have normal o2 sensors in there i believe they are cheap ones though me and my dad are thinking about switching the ones that are further back near the headers with the ones that are near the muffler
