well im trying to see the difference in the gains where the exactly the gain is on the 1 3/4 and the 1 7/8. im worried that because right now ill only be header back exhaust that ill be losing a bit of power down low. i do plan on getting a tune so that may help as well.

Back pressure is a myth, you set the tune based on your requirements.
on a STOCK LS1, there will be no diff, even on a large cube motor, you may see a hp or 2.
On a bud's 402 high comp motor, he removed a cat back and put turn downs on, didnt gain any hp but the power band moved (shifted).
He will be going from 1-3/4" to a stepped system, i'll see if he can chime in
