Visual/Physical Inspection
- Inspect for aftermarket or non-OEM devices such as, but not including; tailpipe extensions, headers and exhaust cutouts. This could affect the operation and proper performance of the exhaust system.
- Verify the exact operating conditions under which the concern exists. Note factors such as engine RPM, engine temperature, engine load and frequency of concern.
- Inspect the easily accessible or visible system components for obvious damage or conditions, which could cause any symptom.
