I have the exact same setup and am confused myself....it seems to be the 1 7/8 is the way to go, i think 1 3/4 is for forced induction setup, i could be wrong but thats what im taking from other peoples conversations.

the 17/8 will give you more upper hp and the 13/4 will give you lower rpm tq
from what I under stand

The general theory is 1 3/4 for lower HP applications (Below 500hp) and
1 7/8 for higher HP applications (over 500hp).

But the majority of Camaro owners are going with the 1 7/8 headers and they are seeing excellent results. So I would just go with 1 7/8 headers. They will also allow for more serious mods in the future.

1-7/8" is the way to go after doing back to back testing. 1-3/4" was down at least 10 hp throughtout the entire curve. There was no tq loss with the 1-7/8" they responsed as well as the 1-3/4" down low.

I have a short system with headers and connection pipes that will work with your cat-back.

If I can help with anything else please let me know.

I was wondering the same thing when I'm ready to order my headers.

Guys, Superchargers love the bigger 1-7/8" primary as well. It works for every other LS based engine. The 6.2L are no different.
