Step 4: 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.) Now the muffler assembly can be
tack-welded to the catalytic converter extensions.
Once the muffler assembly is tack-welded to the
converters, you will have to unbolt the catalytic
converters from the exhaust manifolds and lower the
entire exhaust system. This will allow enough space
to properly finish-weld the muffler assembly to the
catalytic converters. The catalytic converters can then
be refitted to the exhaust manifolds (Refer to the car's
shop manual for proper torque specifications).
Step 5: 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.
