Step 1: To begin the removal of your OEM exhaust

system, unbolt the pipes from the mounting bracket

located behind the cross-member (mouting bracket

will no longer be used). Unfasten four bolt flange from

manifold & the tail pipe/muffler assemblies from the

OEM rubber insulators and remove.

Step 2: Install your new MAGNAFLOW system by

mounting the supplied adjustable hangers to the rear

cross member with the supplied fasteners (use these

hangers to set the correct oriention for clearance and

aesthetics). Next, attach the Y-pipe assembly at the

flange junction to the rear of the converter with

supplied hardware. Next, slip the D/S & P/S mid

pipes onto the Y-pipe assembly and secure with

supplied 2.50" clamp. Finish by installing the muffler

assembly in a similar fashion. Leave all hardware

loose until the system is fully installed. Locate all

hangers into 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). Inspect all fasteners after

25-50 miles of operation and retighten if necessary.
