This weekend I am going to the track and want to put a test pipe on just for a few runs. I have a 99GSR (obd2) and the factory cat has 2 02 bungs. The skunk2 test pipe I have only accomodates one. The questions are....Should I weld another bung on, should I do the temporary tinfoil trick as mentioned in several other threads, or just zip tie it up for the several runs? If I zip tie it up and the cel light comes on will the comp go into a protection mode?
