There are plenty of threads on the net where stock LS1's were dyno'd back to back and gained power with 1 7/8 over 1 3/4.
I know that stepped headers make some improvement also due to antireverb/back pressure......I've played with the stepped exhaust on my bikes and noticed considerable gains in torque....havnt seen much info on stepped truck headers though....if gains can be made by stepping up to the bigger tubes I would go for it but its gonna take a little shopping to find the tubes and the fit in one package....
Heres a link!!!

These are always an option too.

I am trying to find answers on fitment but I can't find anyone that bought a set. They range from 1.75" to 2" primary tubes including stepped versions. Might be something to look at.

with the Shoenfeld headers, can you just drop them in from the engine compartment without moving the engine? Or do you have to unbolt the mounts and pick the motor up?
They will bolt right up.. no moving anything...
