MagnaFlow GMC DIESEL DURAMAX, 5in. SYSTEM AL Custom Build Pipe Kit Diesel PERF. EXHAUST - Manual

Step 1: (Carefully read all instructions before
installation) To aid in removal of the OEM exhaust
system, you may need to cut the tailpipe from the
muffler. Once this is done, remove the tailpipe from
the OEM rubber isolators. Do not damage the OEM
rubber isolators, as they will be reused to mount the
new system. Remove the remaining components of
the exhaust leading up to the turbocharger. Take care
not to damage the OEM V-band clamp that fastens the
downpipe to the turbo, as it will be reused to mount
the new downpipe.
Step 2: Using the diagram to the left, determine
which pipes are needed based on the cab/bed layout of
your truck. Trimming the the pipes will be required
for models with an X-Tra cab and/or short bed. One
the pipes are trimmed, if required, you can begin
installation. Install the new downpipe by fitting the
welded hanger into the OEM rubber isolator, and by
fastening the inlet to the turbo using the OEM clamp.
Leave all clamps and fasteners loose for final
adjustment of the complete system. Working
rearward, install the Inlet Pipe Assembly by fitting the
welded hangers into the rubber isolators, and by
fastening it to the downpipe using a supplied clamp.
Install the remainder of the new system in a similar
fashion.
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). Inspect all fasteners after
25-50 miles of operation and retighten if necessary.
