LG Motorsports LG Pro Long Tube Headers - Manual (Page 5)

Figure 7: Removing manifolds and cats.
Install:
Before install, take this time to install your front 02 sensor extensions onto the car
harness where you unplugged the factory sensors. Now you can start by installing the
driver side header from the bottom side of the car. The headers should slide into the
engine compartment by pointing the collector towards the inside of the car and down, and
rotate into place. You can ‘hang’ them from the head bolts until you can go back on the
top side. I suggest installing only a front and rear bolt with the gasket first then only
starting the rest of the bolts before installing the rest of the system. Once the headers are
there you can install the sensors and plug into the extensions.
