They weigh about the same...7 to 12lbs each. Dont remember exactly but there is not a big difference in weight.

Dropping the Manifolds and Cats is a pretty big wieght reduction on these cars. Together they are very heavy items. At least it is that way on the LT cars.

The cats weigh the most. The headers and manifolds weigh within 3lbs of each other...

My stock '92 manifolds weighed in at 28.5 lbs for the pair.
A set of Hooker shorty's weighed 11 lbs.
I never weighed the longtubes. They weigh more than the shorty's, I'm sure, but remember that they really replace most of the stock cat/pipe assembly, so you need to consider that when comparing.
