Instruction Manual

Step 1: (Carefully read all instructions
before installation). To remove the OEM
exhaust system, loosen the clamp attaching the
muffler to the catalytic converter extension pipe.
Disengage the welded hangers on the muffler
and tailpipe from the OEM rubber insulators,
then remove the muffler and tailpipe (Do not
damage the OEM rubber insulators, as they will
be re-used to mount the new system.) You may
need to cut the tailpipe approximately 1" behind
the muffler to aid in removal.
Step 2: Install the new inlet pipe using the
OEM fasteners and supplied flange. If you have
a Crew Cab truck install the Extension Pipe
using the supplied 2.50" Clamp. Install the
threaded hanger and rubber insulator as shown in
Fig 1, then Install the Muffler Assembly fitting
the welded hangers into the rubber insulator and
fasten it to the inlet pipe using the supplied 2.50"
clamp. Leave all clamps and fasteners loose for
final adjustment of the complete 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). You
can now connect the battery, start the vehicle,
and check for leaks. Inspect all fasteners after
25-50 miles of operation and retighten if
necessary.
