WARNING: Do not re-use any fasteners that are worn or deformed in normal use. Some fasteners are designed to be used only once, and are unreliable and may fail if used a second time. This includes, but is not limited to, nuts, bolts, washers, circlips and cotter pins. Always follow the recommendations in this information, replace these fasteners with new parts where indicated, and any other time it is deemed necessary by inspection.

NOTE: After exhaust system repairs, make sure that the system is mounted without stress or preload, and that there is sufficient clearance between the system and the body. If necessary, loosen clamps and align mufflers and pipes to obtain sufficient clearance to body and balanced loads at hangers.
