carboman has a little shameless behaviour in the past
Vette Doctors offers a good product of their own design. As for install you could bribe Glenn and I to do it. So what's the problem? 505Hp is not enough? You'll want to get the car dyno tuned as well. You could drive up to Vette Doctors early in the morning, they could do the header install,l dyno tune and have you home for dinner. I'll bet they will cut you a good deal on the complete package.

LG headers work great on the new Z06's.

I have the Vette Drs(American Racing) off road(no cats)
headers.Dale Cherry installed them & I'm really satisfied with the results.You'll definitely want a tune after installation.Although it was very generous of Mark to offer his & Glenn's services to install them,I think this is a job for professionals.I don't doubt their ability or enthusiasm,but after seeing the recently posted pix of Mark's home "lift",
I think this would be a little too much(would provide an interesting video).

Talk to Carmen at the Vette Doctor, they have a header system that has shown to to be as good as or possibly better than LG. The system has been endorsed and tested by Ligenfelter <sp>. I would not hesitate to use them and the price is considerably less.I have lg's on my 03' and they are great. I have been up to the Vette Dr for some work to be done and they are impressive. This is not a shop with a dozen guys working on your car. Only three people keep that shop going. When I went up I had n appointment at 8:00 AM, I left home early in the morning to beat the traffic and was waiting for them to open up. They started on my car, as soon as they moved about 10 vettes out of the garage. If you are doing headers and a tune you will be home for dinner with no problem. They allow you in the garage to watch everything they do.
I had taken my 03' to a local shop to have my headers and tune done. I had horrible resonance in my exhaust system when I picked the car up. I took the car back to the shop three times and they could not fix it, they told me it was the headers that were no good.
Months later I went to The Vette Doctors to get some other work done. The Corsa pipes had to be removed to get to the torque converter. When they pulled the exhaust down they immediately saw what the problem was that caused the resonance and there were also two exhaust leaks where the pipes had not been fitted together properly.
While I was there I asked Carmen to put the car on the Dyno just to see how the previous "tune" showed. Carmen redid the "tune" because there was actually a lack of horse power in the mid range. When he was done I ended up with an 8 HP gain at the top of the curve but most important he picked up 25 HP in the middle of the curve.
Needless to say I would not hesitate to drive back to the Vette Doctor for anything. You can be assured it will be done right the first time and you will get your car back without scratches and nicks. If you go there once and watch them work you will see what I mean.

Jim

You sound as though installing headers is difficult?

It's NOT

The tuning is the part I can't do...

I have a lift that makes it easy.
It's just time consuming.....

Good idea to put thermal sleeves on the plug wires at the same time.

Does the car have some kind of air induction? That is someting else that should be done before getting the tune. Then everything will be done. If you get air induction later you will have to pay to get another tune. Steve Spencer has said always get all the mods done prior to the tune.

Thanks for all the replies. I'm not surprised though. Many good points.
Many of the forum guys are doing headers, cold air and cam.
Oh, what will that cost? And for what? I don't race or whale on it,
I treat her like a baby. However, I'll hang it out once and a while and
just love to hear the exhaust!
With all that in mind, will these mods mess with the warranty?
You are correct Mark in asking is 505hp enough? Yea it is, but but but...well you know.

I would love to do the headers in my own shop but with somebody
who knows what their doing...Mark and Glenn??

Again, this is all thought at this point. But! keep your thoughts coming!

Thanks Guys, ts

Maybe 500 hp at the rear wheels is enough, and with good long tubes and tuning you can get there. I am sure Mark and Glenn could do the job as long as there are no surprises.

Talked to Spence about headers and my factory warranty. Steve told me
the two don't go together. Even a tune could void the warranty.

That's a first, I never had any warranty issue by adding headers to my Corvettes or other cars, some dealerships install headers.

Steve's pulling your leg.

If the headers were the cause of a warranty claim, then that could be a problem, otherwise, no way could they void your warranty.

Your warranty for instance covers the electric window mechanism. So, say you brought the car in because your window would not go down. Do you think they could void the warranty claim becasue you have headers?

They'd have a pretty good fight on their hands if they tried that one...

I hear ya Glenn. If I were ready to install now, I would take that question
much further. I just seemed odd in the way he answered me. Maybe he was
having a bad day.

My experience at Bryner has been that only the relevant part of the warranty is voided.In my case,any issues related to the drive train are excluded.If you increase the hp by adding headers,they may take the same position.

it is at the dealer's discreation, most dealerships wont void the warranty because it's all the work they can get now. Really where you run into problems is the specific area of the mod, but most dealerships wont stick you on it

There are several laws protecting your right to install aftermarket parts (mainly the Magnuson-Moss Warranty Act). The key point being that the dealer must prove the aftermarket part caused an otherwise covered failure. In any case, they can't legally void your entire warranty. The thing to keep in mind is that anything that increases HP can be proven to cause damage to your entire drive-train, sub-frame, suspension, etc. Basically, it all boils down to your relationship with the dealer, and their relationship with the factory rep.
