the system to ensure that no part of the exhaust is
in direct contact with the chassis or body; adjust-

14. Return to each of the Clamps and tighten with a
9/16” wrench. Again, do not over tighten Clamps.
Having any part of the exhaust system in direct
contact with any part of the body
or chassis will the cause the ex-
haust to rattle.
IMpoRTaNT: Do not over-tighten clamps. Too much torque will result in deformation of the exhaust. For best results
when doing the installation, tighten the clamps enough to hold the exhaust pieces in place, but don’t tighten down until
the entire exhaust system is installed.
