C5 w/ Borla straight pipes, O2 sensor code
Sorry, first post. I'll try to get this right.
I have a 2003 C5 (LS1) with the Borla exhaust mentioned above. Of course, it's throwing a code ofr missing O2 sensors.
Is the a workaround to fool the computer and eliminate the CEL?

The Borla straight pipe axle back shouldn't have any effect on the O2 sensors. Do you still have the catalytic converters on the car?
It would be helpful if you post the code. If you have p0420 or p0430, which are downstream O2 checks, those can be turned off by a tuner. But if you still have the catalytic converters, something else is causing you a problem.
