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.
