same as all the other headers. do a search for pacesetters on ls1.com as there is a before and after dyno there.

i too am interested in these headers, but have heard problems about fitment issues.

read my install notes in my sig to see the "fitment" issues

my friend dynoed 350/365 in his O2 Z with pace....and a TSP lid

fitment not so great, they rub on the k member

We've seen 24rwhp, but the last one did 31rwhp. I think its pretty much because it had 98 95k mile cats before!!

Mine fit with minimal grinding on k member and they tuck up really tight, and havent dynoed yet, but the sotp gain is noticable.

My headers fit fine. The Y pipe was junk though. I spent so much time on the Y pipe cutting and welding that I just said " to hell with this crap, I'm building duals". This was one of the best decisions I've ever made. I didn't do any before and after but the headers with the duals gave me GIANT SOTP gains. BTW, I have another set of duals for sale in the parts section.
