Do headers make sense for a bolt on only C6Z?
why are some guys making as much or more power with a simple tune and cold air intake as those who have CAI,tune,and headers?

they are nice headers for sure. i used to have a set.
my point is, when some can make the same or even a little higher power without headers and as those with headers on the same dyno, you gotta ask if the $1800 set of headers is worth it

This is a controversial subject as you will discover when you do a search. Most of the naysayers are those that do not want to pop for the $1600 plus install for the headers. Get ready for a lot of "this dyno" vs. "that dyno" stuff and then make your own decision.
Headers are not Smog-certified in some states, so act in accordance with the laws of your state.

We have installed close to 25 sets of headers on the LS7 and they all made big torque in the sweet spot. Not one didn't gain any power. Typical TQ with a tune is about 450-460. Headers get you to 478-485 and its through the curve. Yes a ported intake and TB brings the power up a bit. No real debate about this. We are doing a 06 and 08 this week. If I think about it I'll post the gains stock vs tune vs. headers. We have been baselining, tuning and then header install and fine tuning. This way the information is more conclusive. After 25+ cars you start seeing a pattern!

The reason you want all those thing done is simple. Bigger intake more power.

make sure you're comparing from the same dyno, and hoepfully same weather type conditions. That alone can account for head scratcher type results we sometimes see on the forums. I have a stock exhaust manifold/cat c6z that makes about 485/453 at HPP dyno with cai, ported ls7 intake/tb and pat sparks (qmac) tune. But I have no doubt if I added headers, the mid range will pick up fairly dramatically. Probably not alot of top end hp increase (maybe 10-12...), but surely more around town tq yanking capability.

How long to you plan on keeping your car?
A possibility of some or more warranty loss?
Will there be more engine mods in the future?
Even if you could get that extra 15-25 (assuming, or better curve in power), one should consider all factors...
I did, to point of no return

There are many different factors that can affect your dyno numbers. But as far as the headers go, you may get a gain out of them just from slapping them on but you are wasting your money if you do not go the extra mile to get a Tune. And then, different tuners can get different numbers. For the sake of keeping everything civil, it may be better if no name brands are mentioned, else there is another riot on the C6Z06 forum.

When you compare the pieces side-by-side, you will see the difference.

Check back through the archives, most guys were only getting 3 to 4 HP for a stock Z, it didn't matter which headers they were using. Something to be said for the factory exhaust system.
Now if your going to add some mods like a cam, I would be doing headers, had LG's on my C5Z and you could really feel the difference but I will wait for headers on my C6Z until the cam goes in.
