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. Begin by removing all exhaust components from the shipping container
including the clamps.
2. Locate the two hanger brackets in the hardware kit. Install the rubber grommets saved from Step #7 of the removal
process (Fig. J) and mount the brackets on the vehicle using the bolts saved from Step #3. (Fig. K)
Note: Ensure the U bent hanger is towards the front of the vehicle when mounting!
3. Locate the passenger side tunnel muffler and one of the supplied 2.5” clamps. Slide a clamp over the expanded end
of the muffler with the bolt opposite the hanger. Slide the expanded end of the muffler over the passenger side
front exhaust pipe. (Fig. L) Insert the muffler hanger into the grommet. (Fig. M).
Note: The use of a soap and water solution may aid in working with the rubber grommets.
4. Locate the two bolts, two nuts, and two washers from the hardware kit along with the driver’s side tunnel muffler.
Begin by inserting the hanger into the rubber grommet. Slide the bolts into the holes of the flange on the tunnel
muffler such that the bolt head is towards the rear of the vehicle, followed by a washer, then the nut on the front
side of the factory flange. (Fig. N) Hand tighten both nuts and bolts.
5. Locate the XO pipe assembly and two more of the supplied clamps. Slide the clamps over the expanded end of the
XO pipe such that the bolts are towards the inside and then slide the expanded ends of the XO pipe over the outlets
of the tunnel mufflers. (Fig. P) Ensure the flat bracket on the XO pipe is towards the ground. Snugly tighten the
clamp on the passenger tunnel muffler and the two clamps on the XO pipe using the 15mm socket and ratchet.
Note: At this point, the XO pipe assembly needs supported using a suitable device.
6. Locate the two axle pipes and two more of the supplied clamps. Slide the clamps over the expanded ends of the
axle pipes and slide them over the outlet ends of the XO pipe. (Fig. Q) The plane of the bend on the axle pipe
should be roughly parallel to the ground. Once the axle pipes are rotated correctly, snugly tighten them using the
15mm socket and ratchet.
