Is anyone running LG motorsports LT headers on a Z06?
An what is your impression of the product? Are they worth the extra money? More HP or not vs the others out ther on the market?

 

ttt!

 

hmmm :seeya that lack of responses answers my ?'s Looks like I will go with the Belanger's :cheers:

 

I have the FLP system and am very happy with them. I know of one individual running LG's headers on his '02 Z06 and his car is heavily modded with a solid roller stroker motor.

 

They have the best collectors, longest tubes, and make the most usable torque. If you race, there is no other real choice, for the street, the extra power may not be worth the extra $, that's a personal call.

For us 380 rwhp, and more importantly 372 ft/lbs on an '01 Z with a sidewinder intake, and no cats/mufflers (race trim) with no computer tuning. The hp number was great to get, but if you research some, you'll find 390-400rwhp cars that barely make 370 ft/lbs.

Customer support and service is excellent, especially if you can get the install done in house. I doubt it's the easiest install due to the extra long tubes and tight fit, but the end result works well for us.


:cheers:

 

We have had great results with the headers on Z06/LS6 motors. On some of the larger CID motors we have has gains of 20+ HP over competitors headers. Please call the shop at 972.272.7753 and ask for Lou for more information.

 

The one thing that interests me the most about the headers is the extra increase in torque over the other products out there. HP gains are nice but, I am also after the most torque I can possibly get.

 

I have been looking around at a lot of the C5s and the header that are on them. I am currently looking for a set for my dad's '03 Z06 and LG's are by far and I mean BY FAR the best header you can get for them. I would say they are the only ones. I have looked at and worked on cars with TPIS, those Bellinger or what ever you want to call that mess, and one other companies headers (sorry don't remember the name off the top of my head).

I have talked to Lou about them and they do hand fit the headers, hence why they cost as much as they do. And they really do fit in there nicely and all of the clamps, cats and offroad pipes are very nice as well. And its all stainless to boot.
:cool:

I have seen a couple dyno runs between them and the LG headers by far make more power under the curve than anyone else's headers.

When ever we get around to doing the headers on his car I know who's I'm going to get. LG's all the way...there is no since in half butting it :thumbs:

 

Thanks for the kinda words, Lou works hard on them. :cheers:

 

I would not say anything bad against Belanger headers, they were the only header out of the 5 that were on my car that made over 400 hp, the LG's were not available when Peterson wanted to do the magizine article on headers for the C5 Vette, they also made the most torque of the 5 tested. :) The LG headers are good looking for sure.

I have been looking at the LGMs simply because they appear to be the best design. The only negative response I have heard was from one of the shops in Houston. Their complaints about the header were the following.

After installation they made less HP than the TPIS headers they replaced.

The 02 was so far back they had issues getting enough temperature to have the 02s staying lit off.

The collectors came back so far that it made for more modifications and the use of the high flow cats.


With that said, they said they felt they were probably best for a "race car" only setup where exhaust heat would be higher, and cats wouldn't be an issue. Now, let me also state that they havd only done one set of LGM headers, and a bunch of the others.

Now, which header am I looking at. The LGM. I want all the torque I can get. I also feel like there are some HP gains with the LGMs that you can pick up over some of the other brands. If I couldn't get the LGMs I would probably go with the Stanless Works headers. Remember the motor is a whole package build your package with the whole picture in mind. If you buy the biggest and the baddest in every category you might make less power than if you carefully select your parts to make them work together.

This is especially true when you try to put H/C and headers together....

We haven't hid the issue but we have refunded or repaired every set of headers with that problem - some of the intial batch of headers had collectors that leaked which freaked out the O2 sensor and may have cost power. All those headers were replaced and we have the system down to a complete science now. If whoever is doing the installation has to custom weld in some cats, I can see how it would be an issue. Also we are offering O2 sensors that work best with the headers now too. Our system is complete with v-flanges for interchangeable straight pipes, cats, and an optional 3" x-pipe. If you want the most power possible we offer the ultimate C5 header available for the money, but there are other alternatives on the market. For more details please feel free to call the shop and discuss.

Godspeed

How much for the 3" X-pipe and is it a direct bolt up to the cats ie. is the outlet of the cat 3"? Are the O2 sensors included in the purchase price of the headers? Or are these and additional charge????

 

Not a Z, but my LGM's should be here in a few weeks.
Going straight from LGM to JetHot to be coated.
Got all the toys, from heads to cat-back.
Have not decided to do a before and after dyno yet.

 

I have a 427 C5R Lingenfelter being installed and went with the LG headers. They should be finishing it up this week. The install looked very clean. I should have the dyno numbers by the end of the week after they finish the tuning.

 

Welcome to the Forum Dave :D

Yes, we installed those headers as a complete package (to catback flanges)... and are impressed with the fit and ease of installation. Minor welding on the x-pipe adaptors... but I almost prefer it that way because it allows me, the installer, to align things up a bit better. The high flow cats are excellant quality, small bullet style... and I also like, again as an installer, the fact that the cats have different exit lengths. Lou also provides matching offroad pipes. This means we do not have to fight the V clamps hitting each other. FYI, the Lingenfelter C5R427 with the LG's and stock Ti exhaust sounds AWESOME! Nice lumpy but quiet idle... quickly getting louder as RPM's increase... not an obnoxious sound by any means :) No resonance at all that I could tell.
Hope to have dyno results this coming week.

:cheers:

I like Lous headers on big C.I.D N/A motors a bit over the F:p: jit.On my own c i would have still lnstalled the FLP's and on a base install FLP's for sure.The FLP is a total package for street/strip use Lous headers are race/race/race and they do the best for racing.
The Flp's are a great money saving unit for the Z06 racer bevause he see's,,,FLP brochure and between the Hi- flow X-Pipe and free flow cats and getting rid of the precat for which FLP is cut perfectetly for,you can see alot of the gain right off the bat.Run this system into some Stingers or PRT's and you will se crazy #'s for just exhaust.
Lous system is great for the daily driver The FLP cant be beat and put out some great #'s and unlike lous true long tubes with no precat the intermediate pipe and 02' sims will give you great #'s out of the box with minimal fuss and the LG takes a cut and weld here and there and can be a bit impractical for the street guy and because of there length being the only true long tube if not mounted right they can hiy cuerbs and speed bumps.
For your best price on FLP's call Xtreme at 480-517-4969 we wont be undersold if your looking for a true drag race header LG's are hard if not impossible to beat and sound great too.
We had an exclusive on Bellanger dont know what happened but we dont sell them unless speced out on a job they seem to average 3 HP at the wheels and do nothing more than make nice noise,if you want them call us at 480-517-4969 for your best price.Thanks Dave S. Xtreme M.S. 480-517-4969

 

I decided to spend 800 bucks on my TPIS headers that make almost if not the same amount of power as the LGs. The LGs might look nice and all, but the headers are under the car anyway. Who would spend an extra $1500 for a possible 5hp/tq unless you are stinkin' rich?

 

We're doing a G5 H/C package right now on a 2001 Z06 that came in. It had Belanger headers with multiple exhaust leaks. Oops. :lol:

I believe the x-pipe is ~300 bucks and shares the same v-flanges so it can be swapped out with the cats too. Give the shop a call and Rick can quote you an exact price. The 02's are a little extra since some people prefer to reuse their own.

Funny you should say that we just installed a set this weekend that had the same jet hot treatment all the way back. The results? My God they were the most beautiful thing I have ever seen! The owners name was Dennis and he had a compelte G5 package done also. I wonder if he is around here and could post some pics.

Congrats on your header choice, it shoud be quite a package!

FYI for those who are not professional installers like Nate the v-flanges are indexed - you don't have to worry about them magically lining up. Our system is now complete all the way to the catback!

Dave cut down on the caffeine or wait a few hours after the adrenalin rush of driving your car before posting! I just wanted to comment that our headers do have cats available so they don't just have to be used at the track, although they will get you a victory on the track. We have many customers who simply want the best header available on their street car. The FLP system is nice, but only 75% of the way there. Why not pay a little bit more and get the best system available for your C5 and never have to worry about it again regardless of what other mods you do?

1. We have had gains of 25RWHP on modified cars OVER TPIS headers.

2. Who would spend 50k on a Corvette? Or spend 10k on chrome accesories under hood? For the best bang for the buck go with TPIS. But if we applied that philsophy to the cars we decided to buy then we would have all bought Mustangs instead. Sure they cost a little more, but in the real world you often get what you pay for and with the LGM headers we surpass everything currently available on the market - proven many times over.

Not disrespecting or flaming, just an honest question: I've heard the LG's have ground clearance issues? It looks like "the hot setup" no doubt, the headers look great and very well thought-out and I'm sure they deliver what they're claiming.

From the under-car picture on LG's site, it doesn't appear to hang lower than anything else, but I've seen this issue brought up before, and it may make a difference in choosing a street system. I have the FLP's myself, very pleased and not looking to change anytime soon, I would have seriously considered the LG's had I been aware of them prior to buying the FLP's. I know I've hit em crossing speed bumps at least twice already, and just want to raise this point to anyone considering a header/cat/X-pipe system for street use.

Just mentioning it since it hasn't been brought up here yet.
