Y-Body - 99 LS1 Exhaust Mans. vs. 02 LS6 Exhaust Mans

Has anyone made the switch from the older LS1 manifolds to the LS6 manifolds? Are there any gains with the swap? Can't do headers.

I don't know, but it would be small difference if any. Could you do shorties or mid length headers?

If this for a F-body?

the 2000 and up F-body manifolds flow better than the 98-99 versions.
