INSTALLATION INSTRUCTIONS

CORSA EXHAUST

5. Lift one of the headers up and slide the 4 top

bolts into the header flange to align to the

engine. (This step is much easier with the

help of another person). Start the bolt along the

bottom of the flange to hold it in place. Start the

remaining header bolts by hand to ensure

they are not cross-threaded.

Do not fully tighten any of the bolts at this

point as you may not have enough space to get

a tool on some of the bottom bolts because they

will hit the primary tubes.

6. Gradually tighten the bolts half way, then more

until they are all nearly tight. Once all the bolts

are snug, tighten them to 20ft-lb, working in a

cross pattern starting in the middle at working

outward.

PRO TIP: Tighten all bottom 4 bolts and the 1

top most rearward bolt from below the vehicle.

Tighten the remaining top 3 bolts from above.

Repeat Install Steps 4-6 on the opposite side of

the engine.

7. Reinstall the steering shaft from Removal Step

14 to the universal joint using a ratchet and a

T40 Torx bit socket.

8. Reinstall the front O2 sensors into the collectors.

WARNING: The sensors are fragile and

sensitive to contamination, take care when

handling. Tighten them using an O2 sensor

socket and ratchet or a 22mm wrench. PRO TIP:

The best way to secure the passenger side

sensor is to route the sensor plug behind the

black tape-wrapped transmission sensor wire

near the starter.
