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. Locate the CORSA headpipe assembly and slide the spherical joint onto the factory pipe. Reuse the factory
spherical clamp and loosely snug the spherical joint. Insert the hanger into the factory grommet. (See Fig. I)
Note: Using a soapy solution on the grommet hole will make the job easier.
2. Slide a supplied 3” TORCA clamp over the inlet of the CORSA muffler. Make sure the weep hole is facing down
then slide the muffler onto the headpipe and pre-tighten the clamp. (See Fig’s J, K & L)
3. Slide a supplied 3” TORCA clamp over the inlet of the CORSA tailpipe. From the rear of the vehicle, slide the
pipe over the axle. Insert the pipe over the muffler exit and place the hangers into the factory grommets. Pre-
tighten the clamp. (See Fig’s M, N, O & P)
Note: Using a soapy solution on the grommet hole will make the job easier.
4. Slide a 3” TORCA clamp over the tip assembly and place the tip onto the end of the tailpipe. Pre-tighten the
clamp at this time. (See Fig’s Q & R)
5. Adjust all CORSA components to attain clearance to surrounding parts. Starting from the front of the CORSA
exhaust system, tighten the spherical clamp to 21 ft-lbs and TORCA clamps to 45 ft-lbs using a torque wrench.
6. It is strongly suggested that all clamps be checked and tightened after road testing the vehicle, once the
system has cooled.
