Please be sure to review the attached instructions prior to beginning the installation
process. If you have any questions about the enclosed parts, instructions or
encounter a problem during installation, call CORSA Performance Technical
Assistance at 800.486.0999. Do not attempt to make any modifications to parts as

FIG. B
CAUTION: Prior to installation, be sure your vehicle is parked on a level surface, and the
exhaust system is cool. For safety purposes and ease of installation, we urge you to take
your vehicle to a qualified service center or muffler installer that employs the use of a lift.
All Torca clamps should be tightened using a properly calibrated Torque Wrench. Using an
air impact gun will damage the clamp and reduce its ability to effectively seal the joint. It
may also cause the joint to separate thereby causing damage to your exhaust system and
your vehicle.

Exhaust System Removal:
FIG. C
1.
Measure 1.5” for STS (See Fig. A) or 9” for SRX (See Fig. B) before the
driver side muffler inlet weld. Using a chain cutter or saw, cut the rear
muffler off at this measurement.
2.
Remove the hanger on the inlet side of the muffler from the rubber isolator.
(See Fig. C).
3.
Remove both hangers near the factory tips from the rubber isolators.
(See Fig. D).
NOTE: Be sure to save all rubber isolators from the vehicle. They will
be used to install the CORSA Performance exhaust system in later steps.
4.
FIG. D
Repeat steps 1-3 for the passenger side muffler.
CORSA Performance Exhaust System Installation:
1.
Remove all exhaust system components from the shipping cartons, including clamps. NOTE: There are
two 2.5-inch clamps supplied.
NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the TORCA band clamps and flange
bolts. Failure to follow this procedure can cause nuts to seize on clamps and potentially destroy threads. After
applying anti-seize lubricant, be sure to thoroughly clean hands as lubricant will tarnish stainless steel.

2.
Locate the driver side muffler assembly and one
2.5-inch clamp. Align the clamp as shown
(See Fig. E & F).
3.
Slide the inlet of the driver side muffler over the cut end of the factory
pipe. Have the clamp in position on the muffler assembly, but do not
tighten yet. (See Fig. G).
4.
Slide the two hangers near the tip into the respective rubber isolators.
Spraying the hanger with soapy water will aid the installation. (See Fig. H).
5.
Slide the hanger on the inlet side of the muffler into the rubber isolator.
(See Fig. I).
6.
Repeat steps 1-5 for passenger’s side.
7.
Visually inspect the exhaust system position, tip alignment, clamp
orientation (see exhaust system adjustment section) and exhaust pipe
clearances. Make any necessary adjustments at the various slip joints.

When the exhaust system is in the desired location, tighten all TORCA
clamps working from the front to rear of vehicle. Pay special attention to
the clamp bolt distance from the rear sway bar. (See Fig. J). The bolt
should be aligned as explained in Step 2, but may be rotated down slightly
to avoid hitting the sway bar.

It is mandatory that all clamps be checked and tightened if necessary
after road testing the vehicle once the system has cooled.
CORSA Performance Exhaust System Adjustment Section:
There are two slip joint adjustment points when installing the CORSA
Performance Exhaust system on the Cadillac STS and SRX. Both rotational
adjustments and linear adjustments can be made where the CORSA
Performance mufflers connect to the factory muffler inlet pipes
(See Fig. K). Two misalignment situations will most likely be
encountered. In the first situation, the exhaust tip is sitting too far
outboard. In the second situation, the tip is sitting too low. Try
sliding the muffler expansion off or further on to the factory inlet pipe
approximately 1/16” to fix this issue. Also rotating the joint will effect the
location of the tips. Using this slip joint for adjustments, the exhaust
system can be completely centered in the bumper cut-outs (See Fig. L).

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 CORSA 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.

process, call CORSA Performance and ask one
