Please take time to read and understand these installation instructions.
CORSA recommends that installation of this system be performed by a qualified service center or professional
muffler installer who has the necessary equipment, tools and experienced personnel. However, if you decide
to perform this install, the use of a hoist and an additional person will be required.
CAUTION: Never work on a hot exhaust system. Allow time for the vehicle to cool. Always wear eye protection
when working under a vehicle.
Please confirm that all parts are present before
beginning the factory exhaust system removal
and CORSA exhaust system installation.

Factory Exhaust System Removal:
1. Unbolt the rear sway bar brackets from the rear cross member using
an 18mm socket on the top and bottom bolts. A 15mm wrench will be
needed to hold the lower bolt from turning while the nut is removed.
(See Fig. A). Do not remove lower bolt from suspension.
NOTE: All factory nuts and bolts will be reused to install your CORSA
system, do not discard.
2. Pull the sway bar towards the rear of the car to clear the studs and
rotate it down on the end links. This will give the necessary clearance
to remove the stock mufflers. (See Fig. B)
NOTE: Due to a mid-year change by Chevrolet, vehicles delivered later
in the 2006 model year and beyond MAY NOT need to make the cut
mentioned in Step 3. After completing Steps 4-10, the stock system may
be removed in one piece by rotating the rear muffler to gain clearance as
needed; the cut will make removal of the stock system easier, but is not
required.
3. The passenger side pipe needs to be cut to remove the stock system.
Measure 2.75” to the rear from the clamp on the exit end of the factory
H-pipe and mark the pipe at this distance. Using a chain style pipe
cutter, cut the pipe along the mark. (See Fig. C)
4. Loosen both driver and passenger clamps at rear of stock H-pipe using
a 15mm socket. (See Fig. D)
5. Remove both nuts that hold the H-pipe hanger using a 13mm
socket. An extension may be needed to access these nuts. (See
Fig. E)
FIG. A
FIG. B
6. Remove the 4 nuts and bolts attaching the inlet of the factory H-pipe
to the flanges downstream of the catalytic converters using a 15mm
socket. (See Fig. F)
