Exhaust System
Hot engine! Avoid all movable parts or hot engine parts, exhaust gases,
and/or fluids. A hot engine, exhaust, and/or fluids can cause burns.
Maintenance
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.
Regulatory Compliance
Acts that constitute tampering with the Exhaust System:
Removing or rendering inoperative exhaust system components (such as the
pipes, clamps, etc.).
Air Intake/Air Induction System
Maintenance
Make sure the air intake system is intact. Inspect components for damage,
misalignment and/or leakage. Primary system components requiring noise
related inspection include the air cleaner housing, air cleaner element,
turbocharger, charge air cooler and intake manifold.
Also inspect all ducts, pipes, hoses, tubing and elbows used to interconnect the
system. Special attention should be given to all welds, seams, gaskets, support
points, clamps, couplings and connections.
Inspect all intake system fasteners, brackets, and clamps for damage and
tightness.
Regulatory Compliance
Acts that constitute tampering with the Air Intake/Air Induction System:
