Which cats do you use on the full cat systems? Also - will these headers bolt up to all emissions hardware? Could the headers be used with the stock Z06 cats/and an x-pipe and Ti mufflers?
If so - pricing and expected dyno gains?
I'll admit the Tri-Y is tempting - that set-up generally makes as much more torque as HP.
Thanks.

Not sure I can answer all you questions, but some of them. The Cat back system that is sold with the headers is made by Random Tech. I am running the Z06 exhaust on my vert and it bolted right up, as a matter of fact the alignment of the exhaust pipes was better after the installation than before. I went with a very conservative tune, similar to stock for the AFR, and picked up a solid 25 HP that you can really feel. We did try it leaner on the dyno on a prior run, and I could have had an additional 10 HP but it wasn't worth the risk in my book for engine longevity. As you look at the various dyno's, make sure the AFR is posted as well as there are some dyno queen results floating around.
The installation of this system was very straight forward, no need to even pull valve covers. The front O2's are straight up and down and the wires reach and install with no problems. The rears route and attach the same as stock so no problems there either.
Good luck with your decision.

$%#@!$ It!!! That's a real good price, $300 less than normal as per QTP web-site; that's essentailly a free install right there! I wish I was ready (as in 'had the $$$') to do this now. Alas, property tax, car insurance, and upcoming income tax means nothing fun until summer. From all I've read about these headers (mostly Vettenuts...thanks for that!) the fit, no codes, low-end TQ/HP, 4 O2 sensors, means these are really gonna be a good performer. 
Oh well, maybe a summer sale will get me in!

I am in the process of installing my QTP’s right now. The fit and finish is excellent, and they fit nice ant tight in the tunnel. I would also like to add that Barry is excellent to work with. I had mine coated by Swain Tech and the look great. All of the stock O2 sensors are in stock locations, and the install is easy. Only the starter and alternator need to be removed which takes just a few minutes each.

Gains are 30-35 HP/TQ in the midrange and 25-30HP/TQ peak. This is also with cats not off road pipes.
You will feel the tri y's when your driving. Gives an instant throttle response. You will need new tires from going sideways

I've been reading about your headers for some time. I was wondering if you might have an explanation for why a tune is not required for the use of your headers while still achieving excellent hp/tq gains. Sounds like the AFR stays the same as the factory tune? I find not needing to go into my computer appealing if my understanding is correct.

These really look like a viable alternative - love the thought of LG's, but these seem stealthier for CA smog visual check.
A few final questions - how much HP from headers to stock cats? Price on that? And, anyone in Socal you recommend for installation? Or, do you have a how-to to see if I should do this in the garage?
Thanks again.

The driver’s side goes in from the bottom, but you need to remove the alternator. The passenger side goes in from the top, remove the starter. Once you know the angles to remove and install it literally just take a few minutes to get them in and out. I have had mine in and out a few times. The first was a test fit then removed to get them coated and they’re going back in. Remove the coil packs and plugs to make this easier.

The headers by them selves are $1250.00 retail. We do not have a kit to bolt up to stock cats. But they can be made to fit like the TPIS headers. Call me if you are just interested in the headers.

All, IMO..I think the reason that these headers don`t require re-tuning is the fact that all four 02 sensors are retained along with the near stock placement along the exhaust system.
My belief is that if the computer can read the 02 sensors as GM designed along with the benefits of the try-y design... you get great results without the need for tuning.... the computer is able to do all the work it was designed to do! IMO.
R.P.
P.S. I tried to post my QTP dyno results (dyno charts with summry) waaaaay back before the holidays but was unable to do so due to "major computer problems/virus", which I am still experiencing! The virus keeps consuming all of my memory the moment I purge my files (it appears to be at the server level), anyone have any ideas how I can still post my results?
Thanx for any suggestions you may have. R.P.

Berry, as you can see, I`m still trying to get my dyno charts posted, looks like I`ll finally get them posted soon with the help of ZGuy!
In response to your inquiry regarding canyon driving.... yes, your QTP headers performed even better than I was hoping, specifically torque under the curve and throughout the rev range that I use during canyon driving (1,500rpm-5,500rpm).
Previously with just the Borla cat-back set up the car felt under-powered apexing/exiting turns (aka:anemic), with your headers/cats the car now pulls "real hard" through the apex and rockets out of turns!
Recently I attended the SCMR #18 run here in San Diego (aprox 18 cars attended), mostly country/canyon roads. Running your headers I noticed that I had to back off several times when exiting turns to avoid sucking up too quickly to the car in front of me, includung Z06`s. This is a perfect example of the benefits gained from using the tri-y set-up.
Oh, by the way, still no engine light/code issues!
Keep up the good work, R.P.
