MagnaFlow BUICK REGAL Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1:(Carefully read all instructions before
installation) Unbolt the four bolt flange on the Inlet
Y-Pipe Assembly at the Catalytic converter of the
OEM system. To aid in the removal of the OEM
exhaust system you may need to cut the tailpipe from
the muffler. Once this is done, remove the tailpipe
and remaining components from the OEM rubber
insulators while being careful not to damage them,
since they will be reused to mount the new system.
Step 2: Working from front to rear secure the Y-Pipe
assembly to the catalytic converter using the OEM
fasteners. Use the supplied 2.50" clamps to attach
the two muffler assemblies fitting the welded hangers
into the OEM rubber insulators. Choose between the
side exit pipe assembly or the rear exit pipe in order
to continue installation of the complete system using
the supplied 2.50 clamps and welded hanger
brackets. Leave all clamps and fasteners loose for
final adjustment of the complete Magnaflow system.
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.
