Now move to the front of the car and un-bolt the clamps at the cats at the front of
the car and remove the mufflers from the hangers and the mid pipe hangers under the
diff. You may need to have a friend help you as the mid-section and mufflers is welded
together and removes as one piece. This is heavy so have help.
Figure 3a, 3b: Removal of stock mid section and mufflers
Drop at the front and pull the mufflers out of the rear bumper cut outs. Move to
the front and now we can start removing the factory cats, 02 wires, and manifolds. Start
by reaching up by the transmission and un-plugging the rear 02 sensors, then you can
unscrew the sensors after the cats and set them aside to go in later. Before removing the
exhaust manifolds you must remove the front 02 sensor plug from the car. These are
located at the back of the cylinder head. See figure 5 for this location. There is a green
safety catch as well.
