MagnaFlow For the car
Step 1:(Carefully read all instructions before
installation). To remove your OEM exhaust system,
begin by unbolting the exhaust inlet flange from the
catalytic converter. Unbolt and remove the hangers
from the rubber isolators making sure to retain all
hardware as it will be needed to install your new
MAGNAFLOW performance exhaust system.
Step 2: Install your new exhaust system by bolting
the inlet pipe assembly to the catalytic converter and
locate the hanger to the rubber isolator. Slip the inlet
of the muffler assembly over the outlet of the inlet
pipe assembly. Use the supplied clamp to secure.
Use OEM hardware to secure the muffler assembly.
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 65ft-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.
