I got the LT headers with xpipe installed. The cam is a 220 224 112+4 .570"
1/8 mile track:

Converter and tune all stock exhaust: 9.71@70 with a 2.20 60'
after cam, U drive pulley, dual exhaust: 9.30@75 with a 2.07 60'
Then finally did pacesetter headers and an x-pipe: 9.34@74 with a 2.06 60'

This is a fully loaded and heavy truck (AWD and quad steer). Other mods listed in signature.

I thought headers would do something... My goal was to be at least equal to my wife's stock TBSS. It ran 9.19@78.8 with a 2.19 60'.

Did you get it tuned for the headers?

Yup. TurboGibbs tuned it everytime I changed anything.

Hmm,
blame it on the weather maybe?

Does it feel better?

I noticed a large difference with my longtubes.

I think it's the weather or your exhaust is restricting it too much. Were you launching in 4x4?

It is AWD. The weather was about 15-20F warmer this time. I still thought the headers would more than offset the weather difference.

SOTP it is a little better in 2500-4000.

What kinda times does that 68' vette run in your sig?

95 bright teal

your 60' is better i think its just having troubles moving all that weight. i dont know how much those weigh but if memory serves me right 6000-7000lbs compared to the TBSS 5000lbs, i think if you ditch some weight you would be were you want to be.
also what rims are you on with what size tire?

For those that have HPT, here is a scan. I couldn't ever get a screenshot posted of the pull.
