The truth is, noone has any dyno info at 2000rpm for these different headers.
The only pacesetter dyno with 2000 rpm I've seen is from a LS1 and the torque was exactly the same as stock. Then again, who knows how well these are tuned before and after.
We need a decent comparison and dyno results at low rpm.
I just got my pacesetters from jethot today.
I may dyno it after they are on, but won't be able to get a before dyno to compare.
I can't believe it's taken 7 years to get as little decent header info as we have.

Comp 206/212
Just kidding also.
I hope your Pacesetters don't look like this set:
Thorley has been making headers for decades. I trust he knows his stuff.

Naw, my pacesetters look better than that.
I'll post a buncha crap when I get them on next week.
Speeking of torque, thats why I got the cam that I did.
Y' aint got much to worry about with that 3000 TC.
I'm cruisin at 1500rpm with these 3.42s!
Did the thorley guys tell you they were strongest at any certain rpm? Matches your cam range?
We should chat more later about these Z71s
I considered the tri Ys, but went for the PS full bolt on setup.
I'll give honest opinions after it's all tuned and ****.
Good luck with those.
