How to you access the REAR cat converter for replacement on the 08 ltz 3.6 engine? There's no room to work from above the engine I'm guessing you need to remove it from underneath?

Have you done this before? I can't even see the bolts to remove the heatshield let alone the three bolts that connect the cat to the manifold. All the bolts are pointing upward if your looking at it from underneath. Is there a component you need to remove from underneath the car to have a bit more access to work? Thanks in advance

I have not done it myself. The most I've taken off of my engine was the intake plenum so I could change my spark plugs. The back 3 were a small challenge.

When I needed my O2 sensors replaced, I paid to have them done.
