Step 3: Once a final position has been chosen for the new
system, evenly tighten all fasteners from front to rear. The
supplied band clamps must be VERY tight to properly align

clamps should be tightened to approximately 30-35ft-lbs.
Inspect all fasteners after 25-50 miles of operation and
retighten if necessary.
