I see a lot of you have swapped 5.7 exhaust manifolds for the 6.1's. Did you feel the difference? sound? numbers? would you do it again?
i'm thinking about doing this mod, but would like to hear from some guys that have done it already.

If you do this, buy used SRT "shorty headers" (new ones are more than new JBLs). Some folks have had problems with the O2 sensors - sometimes they have to be moved.
