Installation Instructions
CORSA EXHAUST
14. This step requires the help of another person. While
one person holds and aligns the exhaust tips, tighten
the clamps between the axle pipes and X-Pipe using
the 15mm ratchet and socket.
15. Reinstall the cross braces and bolts near the headers
from Removal Step 15. Install the braces so the
slotted end is toward the rear and outside of the car
and the bolt hole is secured to the subframe. Tighten
the subframe bolt first, using a 18mm socket and
ratchet, followed by the outside/rear one.
16. Reinstall the aluminum under tray using the bolts
from Removal Step 14. There are two slotted holes
toward the middle to loosely hold the tray in place
while starting the other bolts. Start all of the bolts by
hand to ensure none are cross threaded. Tighten
them using a ratchet along with 13mm and 18mm
sockets. Ensure there is proper clearance between
the top of the aluminum under tray and the X-Pipe at
the rear.
17. Perform one final check underneath the vehicle:
●Ensure the heat shield is installed on the steering
shaft and the shaft bolt is reinstalled and properly
tightened.
●Ensure all adapter bolts and clamps are tightened.
●Ensure the O2 sensor wires, and any other wires
are not contacting the headers. There needs to be
proper clearance between all exhaust tubing,
heat shields, and the chassis.
Once satisfied with clearances and exhaust
alignment, lower the vehicle onto the ground.
18. Reinstall the spark plugs using a 5/8” spark plug
socket, extension, and ratchet. PRO TIP: If needed,
properly gap and install new spark plugs.
Reinstall the plug wires, ensuring to rotate and
position them so they do not contact the header
tubes.
19. Reinstall the bolt and nut securing the coolant
reservoir bracket from Removal Step 10. Lift the
reservoir a small amount to install the front bracket
onto the stud and finger tighten the nut on the stud.
Install the bolt in the rear near the firewall. Once the
bolt and nut are started by hand, tighten using a
10mm socket, extension, and ratchet.
20. Reinstall the fuse box tray using the three nuts from
Removal Step 9. Navigate the fuse box tray around
the plastic coolant and PCV hoses and situate it over
the studs. Secure it with the three nuts and tighten
using a 10mm socket, extension, and ratchet. Clip the
aluminum AC line to the front of the box and other
plastic lines as necessary around the sides of the box.
21. Reinstall the fuse tray electrical connectors. The wires
are only long enough to be installed in one location.
They will need to be pushed down and then slid along
the bottom of the tray until they click into place.
22. Reinstall the fuse box itself. Hold the box so the
handles are in the middle and place it over the lower
portion of the tray. Move the handles in and out to
catch the latches, then clamp and lock it down.
Reinstall the battery wires toward the rear of the tray
using the nut from Removal Step 6 along with a
13mm socket, extension, and ratchet. Close the
plastic hood over the connection and clip any plastic
hoses into the fuse box itself if needed.
23. Check over the engine bay one last time. Ensure no
wires are touching the exhaust, all spark plug boots
are fully seated, and all hardware is properly
tightened.
This concludes the installation.
NOTE: Immediately following the installation of your exhaust system, you may experience a trace of smoke after initial
start-up. DO NOT be alarmed. The smoke is caused by the burning of a small amount of forming oil residue used in the
manufacturing process.
