Make sure the exhaust system is intact. Inspect for damage, misalignment and/
or leakage. Primary system components requiring noise related inspection
include exhaust manifold, turbocharger, and all exhaust system (rigid and
flexible) piping. Closely check the system for exhaust leaks. Special attention
should be given to all welds, seams, gaskets, support points, clamps, couplings
and connections.
Inspect all exhaust system fasteners, brackets, and clamps for damage and
tightness.
