Installation of CORSA Exhaust System:
NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the 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 your hands, as lubricant will tarnish stainless steel. All 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
to your vehicle.
NOTE: Align all clamps so that the center of the clamp bolt is 90 degrees from the
notch in the pipe. (See Fig. CLAMP)
1. Remove all system components from the shipping box, including the clamps.
2. From the front side of the vehicle, carefully guide the CORSA tail pipe over the axle towards the rear, passing the hanger
through the voids in the spring. Install each hanger into the factory grommets. (Fig. F, G, & H)
Note: Using a soapy solution on the grommet holes will make the job easier.
3. Locate the CORSA head pipe assembly and the factory spherical joint retained from the removal process. Rotate the head pipe
until the hanger shoulder is parallel to the ground, then snug the clamp at the spherical connection using a 13 mm socket and
ratchet. (Fig. J & K)
Note: Using a soapy solution on the grommet hole will make the job easier.
4. Slide a supplied 3” TORCA clamp over the inlet of the CORSA muffler. Make sure the muffler is oriented so the drain hole is
facing down, then slide the muffler onto the head pipe and snugly tighten the clamp with a 15mm socket and ratchet. (Fig. L &
M)
5. Slide a supplied 3” TORCA clamp over the inlet of the CORSA tail pipe. Slide the tail pipe on to the muffler and snugly tighten
the clamp with a 15mm socket and ratchet. (Fig. N)
6. Slide a 3” TORCA clamp over the tip assembly inlet, and place the tip onto the end of the tail pipe. Adjust assembly inlet on tail
pipe so that tips match bevel of the rear quarter panel. Rotate the tip assembly until tips have equal clearance to the side of
the rear bumper cover. Adjust and rotate the tail pipe as necessary to align tip as desired. Snugly tighten the clamp at this time
using a 15mm socket and ratchet. (Fig. P & Q)
7. Adjust all CORSA components to attain clearance to surrounding parts. Starting from the front of the CORSA exhaust system,
tighten all TORCA clamps to 45 ft-lbs and all spherical clamps to 21 ft-lbs using a torque wrench.
8. Reinstall the heat shield using a 15mm socket and ratchet. Replace the spare tire to pre-removal condition (refer to Owner’s
Manual if necessary), and replace the lock and cover plate in the rear bumper. (Fig. R)
It is strongly suggested that all clamps be checked and tightened after road testing the vehicle, once the system
has cooled.
