Default QTP headers... 1 7/8 or 1 3/4 ? Please see setup inside

mods in sig... doesnt see nitrous much but when I do spray I want the one that will work well with it. Basically X3 cam, stock LS6 heads and bolt ons, true duals etc etc. Will not be going to larger cubes in the near future... possibly heads but not for a while. Im used to the low end of SLPs, which one will not kill my low end, but not hinder the 7000 rpm redline ?

I made the numbers in my sig with 1 3/4 headers. When i talked to the guys down at More Perf. they told me the 1 7/8 have shown roughly a 5-7rwhp gain over the 1 3/4 on a H/C or cam only car. I would say if you are worried about losing low end i would go with Kooks stepped headers, i wish thats what i would have gone with.

Tooo expensive! And I heard the Kooks are hard to get ahold of ? Their website has pretty much nothing as far as pics, info, pricing etc...
