Default Has ANYONE done any sort of Dyno using XS HEADERS?!?

Been looking into a set of these but i can't seem to find any sort of dyno numbers At this point i don't care what other supporting mods you have, if you have XS Headers, post up your numbers along with added mods.

I'm really just trying to see if with these headers people are pushing about the same HP as pacesetter, Hooker, etc. In other words i'm looking to see if Hookers, pacesetter, etc+CAM hp = XS+CAM hp....
Wow, i think i just made this thread confusing as ****

Just post your numbers and mods with the XS HEADERS PLEASE LOL...

I am going to dyno mine before and after. It will be a few months or so though. I know that doesn't help now.
