Step 1: (Carefully read all instructions before

installation) To remove the OEM exhaust system, you

will first need to cut the pipe behind the muffler

before it goes over the axle. Next, remove the ball

clamp securing the Inlet Pipe Assy to the catalytic

converter. You can now disengage the welded

hangers from the rubber insulators and remove the

tailpipe. Unbolt the muffler inlet from the catalytic

converter at the clamp junction. Do not damage or

discard the OEM fasteners or rubber insulators, as

they will be reused to mount the new system.

Disengage the muffler hangers and remove it from the

vehicle.

Step 2: Install the new Inlet Pipe Assembly at the ball

flare using the OEM fastener. Leave all clamps and

fasteners loose for final adjustment of the complete

system. Install the Muffler, Resonator and Tailpipe

Assemblies in a similar fashion using the supplied

3.50" clamps and by fitting the welded hangers into

the OEM 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.
