Step 3: With all components mounted loosely,
adjust the system for overall aesthetics and
clearance of frame & bodywork.
(MAGNAFLOW recommends at least 1/2" of
clearance between the exhaust system and any
body panels to prevent heat-related body damage
or fire.)
Step 4: 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 the pipes and
prevent leaks (Approximately 40ft-lbs). U-bolt
clamps should be tightened to approximately
30-35ft-lbs. Inspect all fasteners after 25-50
miles of operation and retighten if necessary.
