MagnaFlow BMW M5 Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1:(Carefully read all instructions before
installation) To remove the OEM exhaust system
begin by unbolting the two inlet pipe flanges at the
catalytic converters. Working front to rear
disengage all welded hangers from the rubber
insulators and remove the system. Retain all
mounting hardware as it will be needed to install
your new MAGNAFLOW exhaust system.
Step 2: To install your new MAGNAFLOW
exhaust system the Inlet Pipe Assemblies need to
be assembled looseley with the Resonator
Assembly using the supplied clamps first. Install
the completed assembly by attaching the inlet
flanges to the catalytic converter outlets using the
OEM hardware. Locate the four mounting
brackets to the vehicle sub frame using the
supplied hardware. Next slip the inlet of both
Extension Pipes over the outlets of the Resonator
Assembly and loosely secure using the supplied
clamps. Install the two Tail Pipe Assemblies in a
similar fashion. Locate the welded hangers to the
rubber insulators.
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.
