Hi Guys,

Here I go again on that slipery slope, but I do not know any better.

The LG Headers were designed in house by us at LG Motorsports.
We sell them to Katech. They did some dyno work with them against the TPIS, and found 30 ft lb torque increase OVER the TPIS, and at that time they did not even have a cross overe or "X" pipe. I think that they have done the test with the "X" pipe by now.
On Our Dyno on my 7 liter package we found an increase of 22rwhp and 27rwtq OVER the Tpis headers, and On Randy Goss' Cam and head car, we found 17rwhp with the LG Longtubes OVER the Tpis.
-------------
I think that the Stainless Works headers are the best "Mid Lenght" header, for the money ( mid length is what the other header brands are). We have Stainless Works headers in stock and would recomend them over the TPIS, TTS and Balangers.
--------------
On our latest LG Longtubes we increased the flange thickness to 3/8" and added a mounting bracket to hold them in place, and now have an adapter for the rear of the system that eliminates the welding that was necessary before.

This is all just for your information. To build a full 304 Stainless steel True Long Tube header, with a racing "Merge" collector, 3" high flow cats, and 3" off road pipes is not a low priced endevor. You can compare with other brands that have only 2.5" cats and off road pipes.

I built the first set for my own car, because there was no readily available header that, from my racing experience, would perform up to my standards . So we built what we wanted, and now we sell them.

Every other header for the C5 is very similar to each other. They each package them slightly different, but they are much the same. All except the LG Long Tubes.

In the coming months we will devise a lower cost production "Merge" collector that should reduce the price significantly. This new collector will still perform within 1 percent+/- of the race Merge, but at a lower price. Then the price will be in the $1800 range. That should make your decision harder.

And for those of you who need a lower priced system, we will be glad to sell you either the Stainless Works or FLP and match any price out there. We are dealers for both brands.

I have said this all along, each C5 owner has their own set of requirments that meet their needs. Horsepower is not the only factor. But if it is, and you want the most out of what ever mods that you have done to your car, then there is no other choice but LG Stainless Long Tubes. But if after you buy headers, you continue to mod your C5 to find more HP, you might have to wonder what you left on the table by not buying the LG headers.


Please do not use this as a starting point for a flame. I am just trying to get the facts out, and I am not trying to dispute any of the claims or features of any other header.


I am working on a payment plan for those of you who budget your mods, and I would love to help work within your time frame /spending schedule with some kind of payment plan. I will take suggestions

I agree with Matt on this issue. The LG headers are probably the best header out there, no doubt. But imo, they would be best suited on bigger displacement motors. I personally talked with Chris at Katech about the tests on LG headers, and was advised the big gains over TPIS headers were from big displacement motor tests, not stock displacement. That needs to be clear. Chris also told me they worked well and was very impressed with them. :yesnod: They are now using them for testing of their pkgs.

LG- I need two sets of your headers, one for shop use and one for a customer 427 engine swap we are doing next month. Please email me!

Matt and Nate
I don't think that the fact that they are great for big displacement engines precludes them from excelling on stock displacement engines. In fact, my car is stock displacement and the TPIS made 17 less RWHP. To me, that is a lot of hp.

No, they do not build them.

Talk to Lou about some he took back that he has re-engineered consistent with the new design. He is talking about discounting the ones he took back and refurbished.

You do however have a lot of mods on you car which enable it to flow more air, I would like to see a comparison of STOCK headed and cammed cars, as I do not plan, nor do many of the members here, to do heads and cam for a while, and would just like to bolt on another 20hp and 20 ftlbs. of torque. Does anyone have a comparison of these headers on stock headed, cammed cars? :confused:

 

LOU

Once again, I ask, do you have plans of making your setup so that it replaces the xpipe TOTALLY, without having to modify the stock stuff? You talk about peoples needs, and mine are that I need to be able to 1) install it myself with ease, and 2) be able to go back to stock (meaning all stock pieces stay unmolested for the install) whenever I may choose to sell the car.

Right now, that leaves me with FLP, and possibly SLP....when I really would rather get LGM.

What are the plans? The non-race collector thats 100% bolt on, no cutting needed would be awesome.

Whichever brand I get, I'll be doing a fully photographed install writeup on, just like the others in my sig.

 

No problems with my Belangers, completely satisfied for the last two years...

 

Jim,
that is easy enough to accomplish, it would just add $$ to the price, and we are trying to cut the price down now. We will have a full 3" back section, that will mate to a 3" muffler package soon. But I am getting ahead of myself. I will check into what you are looking for. and get back to you.

rrobert22,
I think Jeremy (Goodspeed) has his stock 99 dyno graph in his sig.
It is just what you are looking for.

Thanks,

Lou Gigliotti LGM

 

I wont be wanting a muffler setup, I have the Z06 Ti exhaust and I wouldnt get rid of it for anything right now. If yall have spare stock H-pipes laying around and would sell them cheap then I wouldnt mind cutting one up, my main concern is that I can go back to stock anytime I want or need so I need my stock stuff sitting in the garage at all times.

My 2nd concern is ground clearance. My car is lowered 2-3". I wouldn't want to scrape up a set of $2k headers....how is clearance compared to stock. I beleive I've heard the FLPS only cost about 1/2" of clearance, which isnt good, but I could probably live with it.

Thanks again for the reply...my emails to you must get lost in the sea of emails you get. :confused:

 

BTW, i think you'd really compete with FLP if you guys made it bolt on, ready to go, no modification needed at a fair price. I heard a rumor the LG's would slide in from the top too.....is that true? That would be a very important piece of info for me as well....jacking my car 3 feet in the air is never fun (like I did for FLP's on my 2000 Camaro SS :eek: )

 

Jim
My car is lowered at least 2 inches and I have hit them once or twice. But except for the situation below, only on the clamps. We have since gotten the height of the car right and have no problems. But remember, they are stainless and very tough so a slight bounce on the header would not dent them.

I can speak from experience because when we installed the coilovers they settled much more then we expected. The car was practically on the ground and I hit them several times before I could get back to LG to have them raised up an inch. No dents only some mild abrasions. Very tough headers.
Cheers

Good question. Remember that the engine is only and air pump and you have to address intake and exhaust. So consider and cold air intake as part of your upgrade.
Cheers

Matt, I am totally with you on this!! :yesnod: I too had a set of TTS on my 99 A4 and got more gains out of them than the TPIS on my 2002 Z06.. Not to mention the leaking of the TPIS - ARG! - as I am going to take them off soon..

:cheers:

 

WOW - about three year ago we only had a couple of LT choices - and these days we are looking pretty spoiled on the header choices.. :smash:

 

The question isn't what's the best header for a C5, but what's the best header for a certain engine combo. Quality, ie fit and finish and durability, is one thing, power production is another.

 

No disrespect, but what good is all the rest without power gain? Assuming that all of the top headers are good headers and carry a reasonable warranty against defects in workmanship, the only thing that matters is the power to cost ratio.
