MagnaFlow CHEVROLET CORVETTE Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

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.
