LT headers 1"7/8 vs. 1"3/4 for NA

[CCCP1999]

What kind of HP gains for just the headers on the 5.0? With my 06 C6 Vette i got around 30hp and 30 lb ft gains with AR headers and a dynotune.

I went from 371/355 (bone stock) to 420/395 SAE with just 1 3/4" long tubes and Lund flex fuel on E85. So 49/40 gain.
