Everything has been beaten to death but nothing like headers. poopie usually you dont even have to do a search. Just scroll down the first 2 pages and you are likely to find a header thread.

 

No one forces you to click on any particular post. I say forget the petty lil' 10-15hp differences in cams or headers and just re-jet or turn up the boost. :nopity

 

LG's here and very pleased with the fit and performance gains. :thumbs:

 

I believe that the LG Pro Long Tubes won the Corvette Shootout last month. Torque wins races, Hp sells parts.

The LG Pro Long Tubes are also the choice of no less than 6 World Challenge teams racing in the series this season.

This topic has been beaten to death, but with all headers like all mufflers, and all air intakes, etc, they all do the same job, but they all do it differently with varied results.

We just loaded up the new C5 World Challenge race car to go to Sebring Florida, with our LG Pro Long tubes on the car, and we are looking forward to a great race weekend.

If you are getting LG headers, please make sure that the salesmen know what year car it is so the correct parts get sent to you the first time. We mess up a couple of orders recently, and we don't want it to happen again.

We just got our shippment of headers in from Borla this week, so there will be NO delay in shipping them out.

The new price is $1495 for off road system, and $1895 for the full 3" system with Random cats.

Thanks
Lou Gigliotti LGM

 

Glad to hear you tested the competition and decided on Kook's. That whats on my car and since they out-performed the rest and at a very reasonable price, I'm glad to see a verification of my choice. :cheers:

 

I have to say if I had it to do over again I would get the LG Pros. I have had a lot of problems from the system I have now.

Aaaah HECK! I may get the LGs anyway... Come on Lou, cut a fellow Corvette owner some slack. I need a deal. This system I have has got me beat down!!!
:cry :cry :cry

 

Whats wrong with your stainless works headers? I have never heard one person complain about those before.

 

A few well known tuners on the East Coast did some independent testing of the Kooks, LG's and Tpis headers on some aggressive head and cam packages , the Kooks made the most HP and TQ throughout the rpm band , followed by the Tpis , then the LG's , the LG's did make a few more pounds of torque around 2500rpms though :rolleyes: . The Kooks were on Brent's car which won the tuner shootout last month , if the LG's would have made more power , they would've been on Brent's car , bottom line , don't believe the hype about the LG's , they are a very nice header , but not the best .

 

:lurk:

 

Do the Kook's use all four O2 sensors? Has anyone reported codes once installed?

 

I repeatedly get code P0133 and P0153, Heated Oxygen Sensor (H02S) Slow Response Bank 1 Sensor 1. I have tried new sensors. I have put rear sensors in the front bungs and connect to the front sensor harness with the adapter that Lou sales. There are no leaks. My Air-Pump is working fine.... NOTHING works... :sad:
:cheers:

 

Decision made, I'm getting the Kooks!! :cool: :yesnod: :cheers:

 

I have the kooks and am very happy w/ them.

Care to share the #s from the test?

 

Glad I am having the Kooks installed this week!

:steering:

 

:rolleyes:

So you knew then that the motor had to be jacked up to get the kooks in? Some of us did not know this and had to find out thru trial and error. The guy that helped me had installed 2 sets of LGs prior to these. I had helped him on one set of the LGs.

Now that we know what we are doing I don't think it would be that bad at all, but 15 mins to loosen each motor mount, raise each side of the motor and remove/reinstall the steering shaft????

 

I would go with the Kooks if i had to do it again simply due to the amount of codes my LGM's are throwing. Maybe i am unique and probably not, it must be due to the new (further back) front sensor position & having the rear 02's running up front. My installation went hitch free and I moved the rear sensors forward (with the kit you have to purchase) and they are on the correct side. I double tightened everything and continue to throw lots of "sensor one" codes:
0135 Heated o2 heater circuit bank one sensor one
0155 Heated 02 heater circuit bank two sensor one
0133 Slow response bank 1 sensor 1
1153 Insufficient switching bank 1 sensor 1
1133 Insufficient switching bank 2 sensor 1
I do not know how much these effect my fuel tables or whatever but i know they do & if i go with my original fronts I will have to purchase the wire extentions and re-route all the wiring.
It is a hassle - I had never seen these codes before & there appears to be no easy solution. I recall Lou mentioning the possibility of codes due to the grease or whatever used in the mandrel bending process getting on the sensors....I dont know about that - but I have no idea what to do to alleviate these codes. It would have been simpler to jack the engine a few inches install the Kooks and re-use the right sensors in the right positions.

Anyway they fit nice and look great and sound awesome. But that check engine light is annoying and no way to fix it is even worse.

 

mirek-it sounds like you need new o2's.you sound 100% sure that they are plugged in correctly[you don't complain about any driveability problems].you've checked for air leaks around the o2's.i put lgm's in about 2 months ago[03 zo6]and have been fine.i see that your car is a 00,i dont know how many miles are on it,but FWIW,i would go and get 2 new rear o2's,clear the faults and see what happens.just my .02

 

Thx for the tip. No leaks at all. The car has like 34k on it & no driveability problems at all. I handled the sensors like they were china when they were out. It seems that they are "working" to some extent - I do not think i have thrown all the codes that they would if they were inoperative. I doubt that they would both go at the exact same time anyway. It has to be the new sensor position. LGM has been noticably quite on the issue....not that they are obligated to monitor every issue that pops up & deal with it on an individual basis, but they are very quick to champion their product at every opportunity. I have seen this issue around since the product came out & I noticed it was brought up earlier in the thread. This is an all new position for the sensor...is this a correctible problem on affected vehicles i wonder ?
Maybe I can get some of the new wide-band sensors I keep hearing about. Don't know where to get them or how $$ they are but it is a shame to have to spend even more money getting these pricey headers to not throw ALL THESE codes.
You pay to play I guess.

 

Mirek,

Throwing codes is just part of the "header" equation. It is my impression that once you get headers having an "edit" tune to take care of the codes is the order of the day.

I had my Kooks and drove the car 3 weeks without a hitch. Took the car up to New Haven and came off 95. Came to a stop and saw the "check engine" light. Car ran fine. Pulled the codes and sure enough, they were 02 sensors. Had edit tune 2 weeks ago and so far, so good. I'd be hesitant to blame LG headers for your code issues, as it seems it's just "normal." :cheers:

 

mirek-my o2's are in the same place as yours.the only difference is that mine are newer and i think the part #'s are different between the years.i know that the heaters on the original rear o2's are higher wattages.for ha-ha's did you make sure you didn't blow the o2 fuse?f you did,look to see where the o2's are rubbing/melted,etc.if everything is ok,replace the o2's,and yes,i've seen them both go bad/get lazy at the same time.
