Restricted Exhaust: Notes

WARNING: This page is about a different variant/trim than selected.
NOTE: For dual exhaust systems a quick check of exhaust flow will help determine which side of the exhaust system is restricted. The side that has less exhaust flow is the side that will be suspect, and diagnosis should begin there.
NOTE: For Malibu, see TEST DESCRIPTION - MALIBU .
