Want to install shorty headers on 6L

[denaliman04]

I was looking into installing a set of shorty headers on my 04 Denali with a 6.0L. The manufacturer has a few types available for my truck. They offer a set with A.I.R. and A.I.R plus egr or without either. Is there an easy way to look at my engine to determine if I have these?

If it has AIR you will see plumbing hooked to exhaust manifold near exhaust ports. It will be obviuos if it is present.
