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

Step 1: Remove the OEM exhaust system by first
loosening the clamps attaching the inlet pipes to the
catalytic converter. Working front to rear loosen all
connecting band clamps. Carefully remove the
hangers from the rubber isolators. Be sure to retain
all mounting hardware as it will be need to install your
new MAGNAFLOW perfomance exhaust system.
Step 2: Begin the installation process by first loosely
attaching the inlet pipes of the inlet muffler assembly
to the catalytic converter using the OEM clamps. Slip
the driver side and passenger side mid pipe inlets
over the outlet ends of the muffler assembly pipes
and loosely secure using the supplied clamps. Next,
slip the inlet pipes of the driver side and passenger
side muffler tail pipe assemblies and secure loosely
using the supplied clamps. Next, locate all hangers
to the respective 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.
