So what is the probable case. You have to buy a stock exhaust system and two O2 sensors, hook them all up, do the adaptation drives to reset the values in the ECU and get a smog test.

The maybe worst case is you discover that the ECU has had an ROW flash and you have to flash back to stock after stocking the exhaust hardware. Plus adaptation runs and ECU.

There have to be dozens of stock exhaust systems sitting around because someone upgraded to what you have. Should be reasonable. Get a price from woody aka itsnotanova via a private message on the 986forum.com so you know the hardware cost.
