Yes - that welded protrusion on #6 primary is for the older MY C5. LG just makes one version of each of their different sized models, probably to speed production and get orders out sooner and it allows vendors to stock these rather than having to build to order. Mine are going on my '02 with no AIR setup so I don't need any of those pieces but I decided to leave them rather than chance a leak if I have them cut off and re-welded shut.

Those are our headers in the pictures. We have made changes to them over the years and the early ones did not have the I.D. tags on them.
FYI...for those of you that coat them, we do not suggest coating the cats as we have seen issues over the years with them wearing out sooner with the coating on them as it can cause them to run a bit hotter internally than normal.
ok that makes sense but it looks kinda sloppy to me compared to the picture of Ed's header... and you're right about the air pipe mounts being reinforced, I forgot about that... the newer ones are reinforced but the older ones were not so the owner probably had those added on, no biggie... I wish LG would offer them without the air pipe mounts for those of us who aren't using them... they also do not appear to be ceramic coated as the owner is stating... you could buy a brand new set of LG's or ARH's for just a few hundred more than what they are asking so if you have a bad gut feeling then I would probably go that route for peace of mind
LG does make them without the AIR fitting but these are probally for a 97-2000. And your right they are not worth $1200 and are not cernaic coated. With that said with all the other pieces the seller seems to be so sure of im not buying them. I called LG today and i can get brand new LG streets shipped to my house for literally $150 more. And LG and i spoke about my car and ill be just fine with the LG street series. For $1200 for a old set of headers with no lg plate and air fittings and other issues i have to deal with it makes zero sense to buy them from him. And according to him he has several people that want them this week. I laugh and call " ********". He even quotes in his ad " these will fit many other cars? I think the seller has zero clue about these headers.

Yea these are not ceramic coated. The seller says they are but i can see in the pics they are not. Im not paying $1200 for a old set up that was designed for a 97-2000 corvette. After talking with LG today he said i will run into alot of issues making everything work and fit on my 03 z06. At the end of the day makes way more sense to by a new pair of lg streets direct and have zero issues and have a warranty.

Here's my complete set before coating.
A couple of pics after coating.
And you have to buy block off plates for the air fitting if u dont hook them up or they will leak. And no LG makes the headers specific for the vehicle 97-2000 require air fittings and maybe thats what your headers were for. Im ordering a new set of LG streets tommorow that do not have AIR fittings for my 03 z06
I ordered these specifically for my 2002 recently. This is what LG says is for my C5. Realize these are 1-7/8" Pros so will be different from the Streets. I will be using block-off plates and ORP's. I left the AIR tubes on to keep the option open. I'm in SoCal and may convert this back to on-road at some point.
From LG's website describing the 1-7/8" Pros:
"All headers come with factory AIR injection fittings and dipstick hold down bungs."

Oh gotcha. Thats good to know. In my case there is so many un knowns about the headers i listed and asked about just to much of a risk for $1200. If they were $500 different story.

I think you're making the right decision. Lots of variables making all this work as it is.

Exactly. Not the time to cheap out when its comes to my baby. I was hoping for a good deal, but i think the best deal and less headache is going new. Now my delima is LG streets or ARH? Ive heard the lg streets make better tourque because of the longer primaries. But ive heard really good things about ARH as well. ARH are about $400 more though.
I installed a set of ARH 1-3/4" headers in one of my C5's a few years ago. Excellent quality and fit and the ball/socket joints make for a positive seal and leak-free connections.

Here are a few shot of that installation.
They look great!!! Work of art really. So question is lg streets or ARH on a 03 z06 stock cam / ti exhaust/ basically stock with CAI?
You can't go wrong with either. The installations are similar. I was shocked at how easily my 1-7/8" LG Pros fit in my C5 considering how much bigger they are than the 1-3/4".
Your gains with either should be very close - I think with both brands being great performers, it will be mostly in the tune.
Not comparing the lg pros. Im deciding over lg streets or ARH.
That was the comparison I was referring to as well. I have seen dynos from both brands, the Streets and the ARH's and they were very close, all else being equal. The difference most refer to in the two is that LG Streets make more torque down low (read - street driving) due to the longer primaries but ARH can make it up on top at high rpm. I have installed a set of the original LG's and they were a bit more of a challenge but I believe the newer Streets are better.

Oh man your killing me!!! You telling that really throws me off big time. The lg streets are significantly less cash. Like $500 less. And LG is running a sale right now also on the streets. I personally would rather have the low end torque. Im going to call LG tommorow and find out if the newer streets are easier to install. Do you feel the quality is on par with ARH? As far as welds/ material/ quality of fitment when installed no leaks ect?
Personally, if I were buying with your setup and the price points were that different, I would go for the LG's. They are great headers.
Ok i think ill take your advice and go with the lg streets. Thanks man i really appreciate all your input im all alone in maine and none of my friends are into the performance world i look to my vette brothers for help!!!! 😎✌️
I had the LG Street Series with HF cats and a Z06 Ti on my 00 vert 6 speed and loved that setup. If I can find the clip I will post it so you can hear it. Looking to get the LG Street Series with HF cats for my 04 Z06. Like neutron82 said I would by the band clamps as the one supplied by LG were not to my standards. Overall the LG Street Series is good bang for the buck.
Ok guys here is the conclusion i have made after talking with LG and ARH and real research all over the internet. Are LG headers pretty good yes, do they make power yes, are they at a pretty good price point, yes. Do they compare to ARH, NO!!!!!!!!!! ARH quality is on a different level that LG. All materials are purchased in the USA , thats high quality thicker gauge 304 stainless, way better welds, quality control and fitment. ARH are more expensive but your getting a way better product that will last over time. They fit better so if your having a shop install your going to save money there over other headers becUse they take longer to fit. ARH makes a superior product with top notch customer service. I will pay the little extra and put the best on my vette. We dont own hondas guys we own high end sports cars. Why cheap out with the LG's? It just doesnt make sense. Pay the money and get a quality product. Im going with ARH and wouldnt even consider anything else ever again.
