MagnaFlow AUDI S4 Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: Begin removing your OEM exhaust
system by first loosening the clamps at the
outlet of the catalytic converters. Working front
to rear detach all hangers from the rubber
isolators. Remove the system from the vehicle.
Step 2: Install your new MAGNAFLOW system
by first attaching the inlet pipes of the
Resonator Assembly to the catalytic converter
outlets using the OEM clamps. Locate the
hanger to the rubber isolator. Next, slip the inlet
of the Muffler Assembly over the Resonator
Assembly and secure with the supplied clamp.
Locate the remaining hangers into the rubber
isolators.
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.
