2002 GMC Sierra 1500 Exhaust Systems
Sierra 1500 Exhaust Tip: Most engine control modules - also known as ECMs or engine computers - do not directly measure exhaust gas volume. Therefore, adding a new exhaust system will not interfere at all with the normal operation of your engine computer.
However, if the oxygen sensor(s) are damaged or disturbed during install, this may set a check engine light.
