Visual Inspection

INSPECTION
Inspect exhaust pipes, seals, three-way catalytic converter, muffler, and tailpipe for cracked joints, broken welds, and corrosion damage that would result in a leaking exhaust system. Inspect the clamps, brackets, and insulators for cracks and stripped or corroded bolt threads.
The exhaust system, including heat shields, must be free of leaks, binding, grounding, and excessive vibration. These conditions are usually caused by damaged or loose flange bolts, seals, heat shields, brackets, or pipes. If any of these conditions exist, check the exhaust system components and alignment. Align and replace as necessary.
