You want to find out about headers this is the place to inquire. Stay w/ LGs or Kooks, can't go wrong.

 

I Have People Running Our Product For 5 To 7 Years With Out A Single Problem Lg Car Might Be The Fast 2100 Pound Road Raceing Car I Am Talking Of Real Street Cars And Drag Cars Besides How Are You Going To Make 1 Header For All The Different Motor Combo's Where I Offer Multiple

 

Nick you have a very good point and we use your headers they make very good power and the quality is superb. We also use the dynatech Supermaxx . People tend to overlook this package (headers, high flow cats and xpipe). It is also a very good header and a bargain. I have seen almost identical gains with these headers. For the C6 they offer a 1.875 primary as well as a very long primary tube. When one is selecting the header they are going to use you must also know in what direction you will be going with camshaft in the future. For example with header A you will build more midrange torque and header B builds better higher end HP. In order to optimise the combo have a rough idea what kind of cam you will go with whether it will have a loss of midrange for the high end or will it build best mid tq and taper off up top.

Hi Nick,

I would correct that and point out the weight to be 3000 pounds for the car with LG Pro Long Tube headers that did 140 mph in the 1/4 mile. The 10.4 that it did was even with spinning the tires in 2nd and 3rd or it would have been a 9.90. And all that from a 346 cu in Normally aspirated.



Our headers dominated the front row and Won the race at Infineon in the World Challenge race setting a new record. Plus we got the pole and set a new track record at Lime Rock race last weekend beating out the Factory GM Cadillac team. Our LG headers are used by all the fast Corvettes in the series.

Our headers have made the most hp from a normally aspirated 346 cu in engine in the country at 535 rwhp 482 rwtq. This number has never been touched. And that car did a 10.40 spinning the tires @ 140 mph

Plus the Merge collector helps broaden the entire hp/torque range to counter the trade off of hp and torque. You don't have to choose between high rpm and low end torque. The Merge collector helps both ends.

Here are the features of the LG Pro Long Tube headers

Start with:
$1395 (sale price) for the off road set comes with 3" x pipe and 3" rear pipes plus 3" off road pipes for that price. (Headers, X pipe and rear pipes) not just headers, and all stainless steel from the mufflers up to the engine.

Then more features of the LG Pro Long Tube headers that make them unbeatable:

*** 304 stainless steel pipes all the way back to your mufflers. No cutting of your stock system.

*** 3" Merge collector. Same as used on our race car.

*** Full 3" X pipe that can either connect to 3" metal matrix cats or off road pipes made so you can change to and from cats easily.

*** full 3" pipes supplied to connect to your stock or aftermarket mufflers.

*** 32" primary tubes for good Low end torque. And the Merge collector and 3" X pipe system help the top end flow to achieve the same high rpm results as shorter headers while gaining in the low end where most people run on a daily basis.

*** Easy installation without any cutting and without having to lift the engine off the mounts.

*** Metal matrix cats flow almost double what ceramic cats flow. Metal cats lose about 4-8 hp while ceramic cats lose 10-14 hp. that is why we only use Metal matrix cats. And our Metal matrix cats are a full 3" in and out.

If there were a better all around design, we would make them and use them on our race car and call them LG PRo Long Tube headers. But we have the most hp and highest top speed at each race we go to.

The only improvement that we could make is to use $800 Burns stainless merge collectors which are not feasable for street cars because of their cost. We (Borla) build(s) our headers with a stamped Merge Collector so we can keep the cost down.

The Merge collectors help scavange the exhaust to help pull the next cylinder's exhaust and thus help fill the chamber. It works.

I hope this helps clear the air.

the stainless construction had me sold too..for 2-$300 more i rather have stainless

 

I have only installed a couple hundred sets of headers in the last 10 yrs,pretty much every brand out there and i will tell you the only headers that had to taken back off to be re welded due to cracks are stainless headers. you want long term, go with jet hot coating

 

Of course you could just go with someone who knows how to properly weld stainless. GTAW, DC negative polarity, and Hastelloy filler. It'll never crack if done properly. The Hastelloy filler is key. It is high in nickel, which makes the weld ductile so it won't crack.

 

There have been no definitive before & after numbers posted. LG's have not yet been produced, to my knowledge. I have Borlas with no "X" pipe. I will most likely go with LGs. Been waiting patiently for some time.

Bottom Line:
They are all good Headers.

Kooks all the way
The top tuners all use KOOKs
If LGs were better then you would see more of them on the top tuners cars. Think about that.

 

Off-topic, but just really curious .... why do you capitalize each word?

 

A lot of tuners to use Kooks, I agree, but is it just because they make better margins on the sales? I don't know. Who does... chime in please.
I am looking, I have RK now.

It has nothing to do with sales it has everything to do with performance

 

I've seen others do this and also wondered the same thing. That must be a pain

 

Anyone using or plan to use shorty headers to keep the stock cats? I realize that they probably do not produce the same gains as long tube, but wondered if they produced close to the long tubes.

 

Are these hease any good? I heard they arehaving problems with them on the passenger side. I have a 1999 corvette.

 

OBX is a bargain brand built in China. They initially had some fitment problems but seem to have worked them out.

American Racing, Kooks, and LG/Borla are the top three C6 header manufacturers. HP will be extremely close with all three. In my experience, the American Racing headers are finished slightly nicer, but the Kooks are also very good. LG has had a few problems due to the slip fit design, but proper installation seems to cure it. In the end, shop around and see who gives you the best price as you can't go wrong with any of these three.

 

Ok - 2 big problems:

#1 - You replied to a thread that is over 5yrs old.

#2 - You replied to a 5yr old thread and you own a C5. This is the C6 section of the forum. Duh.

 

I've got LG's and would most definitely go with Kooks next time. My long tube streets went 19: rwh, yes dyno'd before and after. Lg's don't clamp well. Had to remove and relief cut the joints to get any pressure on inside tube. Until I did I could not get them tight or stop the leaks.
Good luck with what ever you choose.

 

I was like, who the hell is bringing this thread from the grave?

I agree you couldn't pay me to put slip fit headers on my car it's just asking for problems
