Step 1: (Carefully read all instructions before

installation) Begin removal of the OEM system by

removing the (4) swaybar mounting bolts at the rear

of the transmission. Do not discard these fasteners,

as you will need them to re-mount the swaybar.

Unbolt the mufflers from the catalytic converter

extension pipes at the 2-bolt flanges. Remove the

mufflers from the OEM rubber insulators (Removal of

the passenger-side heat shield will aid in extraction of

the muffler.) Do not damage the OEM rubber

insulators, as they will be re-used to mount the new

system.

Step 2: To remove the OEM H-pipe, you will need to

cut the extensions in two places. Measuring from

where the exhaust pipes are welded to the rear

portion of the catalytic converters, the Driver's side

pipe will be cut approximately 1" from the rear of the

converter. The Passenger's side pipe will be cut

approximately 3/4" from the rear of the converter.

(See Diagram #2). Do not discard the the OEM

H-Pipe hanger fasteners, as they will be re-used to

mount the muffler assembly. Deburr the extensions

you cut that are still on the vehicle to aid in

installation of the muffler assembly.

Step 3: Begin installation of the new system by

installing the threaded hangers and rubber insulators

as shown in (Diagram #3). Then fit the tip

assemblies hangers into the rubber insulators

mounted on the threaded hanger. The new muffler

assembly will need to be professionally welded to the

OEM catalytic converter assemblies using the MIG or

TIG process. Slide the inlets of the new muffler

assembly over the catalytic converter extensions, and

loosely re-install the OEM H-pipe hanger fasteners to

help hold the muffler assembly in place. Fit the

tailpipes into place over the half-shafts, and loosely

fasten the tailpipes to the muffler assembly using the

supplied fasteners and gaskets. Next attached the

inlet pipes of the tip assemblies onto the outlet pipes

of the tailpipe assemblies using the supplied 2.50"

clamp. Lastly you will need to fasten the two tip

assembly brackets together using the provided

fasteners.

(MAGNAFLOW recommends at least 1/2" of clearance between the exhaust system and any body panels to prevent heat-related body damage or fire.) Now the muffler assembly can be tack-welded to the catalytic converter extensions.
