Installation of CORSA Exhaust System:
NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the clamps. 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 driver side (“D” etch) and passenger side (“P” etch) clamp on elbow
assemblies, along with the driver and passenger side trimmed factory axle pipes retained from the last step in the
removal process.
IMPORTANT NOTE: The AFM valve on the trimmed factory passenger side axle pipe assembly is located closer to
the cut position than the driver side, and both trimmed factory axle pipes are curved to fit around the
transmission on the correct side with the AFM valve at the exit end. The alignment arrow and identification (“D”
and “P”) marks on each clamp on elbow assembly are side specific. Verify that the driver and passenger side
clamp on elbows are paired to the correct axle pipe before proceeding with the installation.
2. Slide the passenger side (“P” etch) clamp on elbow assembly onto the trimmed passenger side axle pipe outlet as
shown, until the edge of the clamp is just short of contacting the downstream weld edge of the AFM valve. Rotate
the elbow assembly until the alignment arrow is pointing at the alignment mark corresponding to the center of the
valve. (Fig. A) While holding the elbow in position, tighten the clamp bolt. Torque to 45 Ft-Lbs. (Fig. B)
IMPORTANT NOTE: Do not over-torque the clamp bolts, as it can cause distortion to the outlet end of the
elbows, which can make the muffler installation onto the elbows difficult.
3. Using a tape measure, mark the trimmed driver side axle pipe at 1 1/8 inch from the cut position. This line is to set
the install depth of the driver side clamp on elbow assembly. (Fig. C)
4. Slide the driver side (“D” etch) clamp on elbow assembly onto the trimmed driver side axle pipe outlet as shown,
until the edge of the clamp is aligned with the depth position mark made in installation step 3. Rotate the elbow
assembly until the alignment arrow is pointing at the alignment mark corresponding to the center of the valve.
(Fig. D) While holding the elbow in position, tighten the clamp bolt. Torque to 45 Ft-Lbs. (Fig. E)
