MagnaFlow DODGE CHALLENGER R/T HEMI Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1:(Carefully read all instructions before
installation) Begin removal of the OEM exhaust
system by cutting the main muffler outlet pipes 11.5"
rearward of the muffler reinforcing brace as shown in
Fig # 1. Detach all welded hangers from the rubber
isolators. Retain all mounting hardware as it will be
needed to mount your new MAGNAFLOW Axle Back
system.
Step 2: Begin installation of your new system by
slipping each muffler assembly inlet pipe over the cut
OEM muffler outlet pipes. Loosely secure using the
supplied clamps. Locate the welded hangers to 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 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.
