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 factory engine mount brackets

using a ratchet and 13mm and 15mm socket.

Passenger Side: Ensure the top bolt in the front

has a threaded stud on the hex end. Reinstall the

ground strap and secure with the 15mm nut

removed during Removal Step 20. Lower the

engine back onto the engine mounts.

8. Reinstall the starter, secure it with the three

10mm bolts from Removal Step 18 using a 1/4"

drive ratchet and 10mm socket with 3” extension

and swivel. Connect the starter wires using the

ratchet with the 10mm and 13mm nuts.
