Early years had double-wall tubular manifolds that might
look like header construction, but unless they are individual
tubes all the way to the floorpan, they are not worth
getting excited over.

`97-`99 had the double wall stainless manifolds, as said above, they kind of look like shorty headers. `00-present have cast iron manifolds that look like every other GM exhaust manifold made. `00-present are actaully better flowing, or so I have been told.
