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. For Base C7 (Non-Z06): Tuck each of the AFM valve wires (front valve on NPP cars) up into the chassis near the back
of the transmission. They will no longer be needed. Secure with a zip tie or equivalent. (Fig. A)
2. Locate the driver and passenger valve delete axle pipes. Install each axle pipe into the chassis as shown. Slide the
axle pipe inlets into the x-pipe section. Rotate the axle pipes until they are centered between the chassis and the
transmission components, then snug the clamps at the x-pipe outlet using a 15mm socket and a 3/8” ratchet,
leaving them loose enough for further adjustment. (Fig. B & C)
3. Reinstall each of the rear muffler hanger grommets as shown using a 13mm socket and a 3/8” ratchet. (Fig. D)
When connecting to a factory NPP exhaust; continue to step 4. If you’re connecting to the factory base exhaust,
skip to step 5.
4. Tuck each of the rear (non-AFM) valve wires into the chassis. They will no longer be needed. Secure with a zip tie
or equivalent. (Fig. E)
NOTE: The driver side muffler needs to be installed first, as the driver side tie bracket sits further forward in the
vehicle. The passenger side tie bracket will nest inside of the driver side bracket.
5. Locate the driver side rear muffler assembly, and one of the 2.75” clamps. While holding the assembly with the
muffler case seam pointed up as shown, position one of the 2.75” clamps such that the clamp bolt is to the bracket
side (inside of muffler) and the nut is towards the ground. (Fig. F)
