Asked by Jun 28, 2019 at 08:33 PM about the 1999 GMC Jimmy 4 Dr SLT 4WD SUV

Question type: Maintenance & Repair

I am trying to modify my exhaust to straight pipe
but I want to know if there's a sensor on the
Cadillac converter that I need to be worried about
other than the one that's on the the motor itself for
the air intake

1 Answer


There should be at least two O2 sensors associated with the catalytic converter. If you disconnect them and remove the cat your car will run like sh*t.
