LG Motorsports LG C6 Z06 Pro Long Tube Headers - Manual (Page 4)

Now install the header on the passenger side to start the rest of the install. The
header should install from the bottom up. The driver side header can also be installed
from the bottom at this time. When both headers have been placed in the car please start
all bolts finger tight as to just ‘hang’ the headers in place. We also only recommend
using GM header gaskets for the 2000 LS1 Camaro as these use the same port design as
the headers and have proven the best seal (there should be a set of ported units with your
kit).
Once under the car it is now time to start installing the rest of the pipes. The front
02 sensors should be installed into the headers and tightened down. You will need to
drill two ¼” holes at the front of the center plate to hold each 02 sensor wire with a zip tie
to keep them from burning on the headers. Please note, it may be necessary to unclip part
of the factory harness to give enough slack and free play in the wires. Install the bell
housing bolts hand tight at this time, as shown in Figure 3. Then the catalytic converters
slip into place just after the headers. Please slide the clamps onto the pipes as you work
your way back so that you can come back later and tighten everything down as you go
once everything is aligned. The X pipe is next in the install. Before installing the X pipe
please transfer the rear stock 02 sensors and place them into the X pipe. Note the
location of the 02 sensor holes and place them closest to the catalytic converters. At this
time it is also necessary to drill a hole in the plate just above the exhaust. This hole will
allow the 02 sensor wires from the rear to feed up above the exhaust and not become
burned on the exhaust. We drill a 1 to 1 ½” hole in the plate to allow the wires to feed
above the plate as shown in the picture below. Please run the wires through this hole and
above the exhaust while installing the X pipe for easiest install. Also make note of the
angle of the 02 sensors themselves. They should lay very close to the X pipe as to give
the most clearance, if not the bungs may have to be ‘tweaked’ a bit to lay them over.
