Currently running Borla Sport Cat-Backs w/ X-Pipe.

If I add Kooks headers, how much louder will I be?

preference is not much, the Borlas attract enough attention.

 

I apologize if I come across saying LG's are “better” than another. I wouldn't go that far unless I have actually tried another header on the C6. I have not run kooks, dynatech, nor any others on the C6 to make a performance comparison. I have seen dyno graphs and the fact that Lou G. has won professoinal races with this header design however. What I do mean by “you get what you pay for” is the fact LG headers are of very good quality, went on without the slightest need for adjustment, gives me the sound I was looking for, and the low end torque is ideal for street use which is where I would benefit most. This is soley my experiance and opinions which I will stand by.

Another big consideration for me is customer service. When I am spending $1700 for a product that requires installation I woant to some guidance if needed. I found that Anthony, Sean, and others at LG Motor sports are actually hands-on guys when it comes to the install and can advise you on every and any question regarding installing of headers. That is invaluable in any product in my book! Not that headers are difficult to install, by any means, however I did have a question regarding routing of the O2 sensor wires and torque pattern and they had the answers with one simple phone call. (Many have even seen Lou himself answer questions on this forum). Perhaps other header mfg co’s offer the same technical knowledge with their phone staff, I wouldn’t know. I can only say I was impressed which is unusual in today’s business climate.

As far as the check engine light goes, yes you can get a CEL because the cats relocation/temp adjustment etc. However the computer relearns itself over time and will eventually quite throwing a code. Or, as most people should do, get your C6 tuned/dyno and program the O2 sensors so there is no issue wih CEL any longer. Lastly, ceramic coating (jet hott, etc) will provide relief for the CEL issue I am told. However I have no experiance with Ceramic coating on LG's to prove whether true or not.

 

What is even funnier is thats where i bought them from !

 

Headers are good. Snow is bad.

 

sick of the farkin snow

 

Poor bastards

 

you guys just got a buttload of it!!!!!!

 

Yes but melting fast !

 

It's loud but not unbearable. I love the rumble at idle and when it screams at WOT. I think you will like it. I'm the same way, not looking for young loud but to at least sound mean.

 

I may wait on the headers ...

APS TT is coming and I WANT ONE!!!!

Dont think I can do that install alone

 

Guys,

After much thought and research, i decided to go with the LG Longtube Headers. Like you I also checked the forum and found that LG had more positive feedback, and not to mention that LG Motorsports is about 5 miles from my house. Also, Anthony, Bobby and all the guys at LG made me feel confident about trustin a $46,000.00 car with them. Attached is a Dyno run with LG Longtube Headers and a tune.................................Man ny

 

Those are definitely nice gains!!

 

One fellow Soldier to Another ....


I am only 3 miles from Springfield...it is my civic duty to break in the 403 for you. I promise to not exceed the speed limit, spin the tires, rev the engine, or other performance based testing.

Trust me!

Ill even make you a video and send it to you
hehe

 

Great power from just a set of longtune headers and engine tuning - you'd have to be happy with those gains.

What difference does the tune make?

Can you run the car without a tune?


The reason I ask is that I am doing my headers soon and want to wait a few weeks till I do the cams to get a tune ..

 

I did Kooks on my C6 and now getting Kooks on my C6 Z06. I think either way you go you will get about the same quality and the same gains. JMO

 

Step into the unknown, I got he BB headers and they are amazing, without tune or ex pipe and with the bullets I was making 376 whp with same tq numbers, now with cam over 420 wheel, I only paid 839 shipped, why dont we dollar cost average the whp with that price

 

no x-pipe? this is prolly hurting your gains.

 

Have You Looked At The American Racing Headers Vette Doctor Series All Stainless Great Fit And Finish Great Power Gains The Guy That Ownes The Company Designed All The Headers For Kooks For The Past Twelve Years Now He On His Own And Builds A Great Product Just Like He Did For Kooks.

 

correct.

If you run with NO cats, then put the X pipe directly behind the collectors. But if you run Cats, then the Cats go before the X pipe.

We pride ourselves on making torque without losing measurable top rpm hp. We could not road race without this long of a header for the low end torque pulling out of the slow corners. Driving on the street is not unlike a road race track.

Our Merge collectors do help the top end to not lose power but a shorter header without a Merge can make more peak hp but lose some bottom end.

The key to our X pipe is that is is a parallel/siamese X pipe, which means that the exhaust has an outlet, and crossover without having the exhaust pulses "CRASH" into each other causing flat spots.

Even on the new 427 cu in 7 liter Z06, we made over 550rwhp and 516 rwtq in a new Z06, so the headers are not limited even with a big cu in engine.

So I also think we have the record for the fastest Corvette with these headers on a road course.

Thanks and I hope this helps.
