5. Locate the passenger side rear muffler, a 2.5” clamp, and the passenger side hanger grommet assemblies
removed during step 6 of the stock exhaust removal process. Install the hanger grommet assemblies on their
corresponding hangers in the same orientation as removed from the stock exhaust. (Fig. S) Next, install the
clamp on the expanded inlet end of the muffler assembly so that the bolt is vertical, with the nut towards the
ground and the bolt towards the front of the vehicle. Insert the muffler exhaust outlet into the exhaust bezel,
then slide the muffler inlet over the axle pipe outlet. (Fig. T) Using a 13mm socket, long extension, and ratchet,
install the front hanger grommet assembly, reusing the stock bolt. (Fig. U) Swing the muffler assembly forward
and install the rear hanger grommet assembly; again reusing the stock bolt. Using a ratchet and 15mm deep
socket, snug the clamp. (Fig. V) Once the muffler is in place, install the ground wire by clipping it to the stock
hanger assembly and the hanger on the Corsa Performance rear muffler.
6. Repeat step #5 on the driver side of the vehicle.
7. Check that the clearance to the suspension mounts are the same on both sides. Adjust the position of the x-pipe
and tunnel mufflers as needed to create equal and adequate clearance of the axle pipes and the rear suspension
sub-frame. Make sure that the x-pipe is level and not rotated to one side. Check clearance between the
passenger side axle pipe and the spare tire well.
8. Locate the front chassis stiffening plate along with four spacers. Install the spacers between the chassis and the
stiffening plate. (Fig. W) Using a 13mm socket and ratchet, install and tighten the four nuts securing the plate.
(Fig. X) There should be at least a ½” gap between any components and the plate.
9. Adjust the system accordingly, including the rear muffler depth and rotation, so that the exhaust
outlets are centered in the bumper exhaust bezels. Check clearance between the system components
and chassis. (Fig. Y & Z) At this time, tighten all clamps to 45ft-lbs using the torque wrench and
15mm socket.
10. Repeat step 8 for the rear stiffening plate. Check clearances between any exhaust components
including clamps to the stiffening plates. There should be at least a ½” gap between any components
and the plates. (Fig. AA)
NOTE: During cold weather start-ups, you may experience an exhaust sound that is deeper and
louder in tone than usual. This is temporary and will diminish to normal levels once your engine
has reached its normal operating temperature.
NOTE: Immediately following the installation of your exhaust system, you may experience a trace
of smoke after initial start-up. DO NOT be alarmed. The smoke is caused by the burning of a small
amount of forming oil residue used in the manufacturing process.
