I originally planned to do LG Long tubes. Buddy is telling me that Kooks are as good, if not better. Tried to search for specs but can’t seem to find anything meaningful, substantive, or credible. Some say long tubes are long tubes, and there is little difference. Others swear by theirs. I can get Kooks @ $400 less than LGs. Both have high flow cats. There is no emission test where I live, so I can go w/o Cats (illegally of course, and please spare me the tree hugger and Boy Scout lectures).

Comments/advice please.

Any other headers worth considering?

And what do I have to do with the O2 sensor to get the most benefit?

Thanks guys

 

Had KOOKS on my C5. Not much written about headers for the C6.
Other than the engine fires on MN6 C6s, associated with the Dynatechs , a product I would avoid like the plague.

The big selling point over on the C5 side of things for the LGMs was their ability to improve torque across the RPM range. Not just peak numbers. Don't know if this is the case or not for their C6 application. This is great if you want to feel the difference in normal driving and not just at the drag strip.

The KOOKS performed flawlessly on the drag strip and were second to none. However during "normal" driving the difference was barely noticable. You had to get up into the RPMs to get the full benefit. SInce I no longer drag race, it is not so important to me.

Points to consider:

Are the KOOKS stainless all the way back? If not, this may be something you wish to consider. May be worth a little bit more to have a totally stainless system. I loved my KOOKS, but if I were doing headers on my C6, which I am not, I would be willing to pay a bit extra, say $200.00, for this advantage alone.

Long tubes are not long tubes. Go stainless steel if you can and consider the diameter of the x pipe. Also I would stick to either LGM or KOOKS if I were looking for headers.


Hope this helps.

 

I was one of the first ones to jump on the DynaTech Sale, by calling it a "Fire Sale".

Jokes aside - DynaTech includes a bracket to hold the clutch slave line clear of the header (as this was the source of the fire, not the header itself). There are "supposedly" 2 models of SuperMaxx - Manual & Auto trans models that take clearances into account.

After installing a set of these myself, when the instructions (and COMMON SENSE) are followed - when it says to make sure that all wires, cables, hoses are clear of the headers - it would behoove you to do so. This was the case in the aforementioned fires - someone didn't do thier due dilligence in assuring that nothing was in contact with the header. The fires were as much the fault of the installer (if not MORE), as DynaTechs. I took extra care to make sure the 02 extensions, clamped the clutch hose, and went back thru my installation carefully to make sure I eliminated the possibility of anything actually coming in contact with hot pipes.

That being said - the pipes are of top quality, installation instructions are detailed and complete, the installation of the X-pipe/cats are clean, they're decently priced, and as part of the "proof of the pudding":

Bone Stock: 336
Stinger/SuperMaxx/GHL untuned: 343 conservatively tuned: 371

#'s talk, availability talks. Someone in the forum had posted that they laid a new LG system & SuperMaxx system side-by-side before installation, and the SuperMaxx was heads over the LG in quality.

Edit: add dyno chart - dyno's may be subjective, but those numbers aren't "variations" between pulls. This was a conservative tune - Jeremy, Norris, Zimmer, etc., could likely have eeek'd another 10-15HP out of it. Also ran @ 97 degrees/98% Humidity (just stopped raining).

 

WOW!!!!!!!!!

I may have to take back what I said about the Dynamax with HP gains like that. I'm figuring the GHLs for 0-5HP at best and probably closer to 0. And the giant air filter for 5-10 at most, (I am not a big believer in oversized air filters like Blackwings and Stingers)

Most of that 35hp gain came from the headers and tuning without a doubt Geez

 

John,

One other thing to consider is the availability of the headers. I, like numerous others, believe that LGM will probably be the best available which is why I ordered them. However, I, again like numerous others, am still waiting for Borla to make them and ship them to LG Motorsports for further shipment to us.

Luckily, I did not order as early as some (I've heard and read of people who have had their order in since February!) but it bugs me to have my credit card charged and still be waiting two months since I ordered with no one at LG able to give me a decent status report.

If you want them now, go with Kooks or DynaMax, otherwise get in line buddy.

 

I'm with SickRick; Dynatech/Supermaxx 1 7/8" is the way to go. All stainless, good fit, easy install (as easy as headers can be). If you follow instructions and use common sense there is little chance of any brand headers causing a fire.

Homemade catback, Dynatech headers, Lingenfelter CAI, NO TUNE = SAE corrected 378.6 RWHP and 370.6 TQ. The headers added 40#TQ at 3000RPM and 15#TQ at 5000RPM. The CAI gains were all above 3500 RPM.

 

You ran 378 WITHOUT a tune? Damn, I was ROBBED...

You running cats, or a straight pipe?

Rick

 

OK Buddy, I understand fully. I'm in line.

Thanks Ben

 

John, don't forget dyno tune day at Abacus on Sept 12th. You had better be there, and I will let you touch my headers!! ........................................ ............Scott

 

It was several fires and with only a few installed sets. At the time kooks were installed at more than a fifty to one ratio and yet no fires. Anybody think that people who buy Kooks are better mechanics than people who buy the supermax headers? They only found out about the clutch line AFTER they actually bothered to install a set on a car with a stick. Which of course was AFTER they were already getting installed on peoples cars. And starting fires. Call me a dick but I prefer it if people that I buy a part from have tried a test fitment on a car like mine. And dont bother with the "in the old days they used to come tossed in a box sans instructions" I was there and installing headers back then. This is now and nowdays we have the ability to make parts accurately over and over. This is nothing new either, the C5 version didnt fit right when it came out. This post is a combination of both fact and opinion. I think most of you can figure out which is which. Here is a sentence that contains both fact, and if you read between the lines, opinion. They will not be getting any of my money, ever.

 

I do seem to recall some of the C5 guys having trouble with the steering shaft contacting the Dynatechs and with the 02 sensors hitting the sides of the tunnel when installed and with the wiring being difficult to route.

I did hear that they had addressed these issues with the C5s however.

 

Yes, they got it worked out. As I said, "when it came out". They probably have the C6 issues covered as well from what I can determine. This must be said in fairness but does not change the facts. I dont like the thought that Im giving my hard earned money to an outfit that couldnt even be bothered to test fit its product on a car for which it was intended.

 

I hear ya. Was yours one of the cars that caught fire after using their headers?

 

I love my Kooks. My only gripe is the stainless looks like crap. But, I don't do bling.

 

With cats. But Dyno differences would probably make up any difference in our readings. Only way to be sure would be to run back to back on the same Dyno.

I'm hoping for another 10-12 HP from a tune once the tuners get a better setup than the existing "Beta" tune.

 

Dynomaxx was the way I went. Absolutely no complaints. I have no interference problems with wiring or clutch line. I can (and have) changed the plugs with no difficulty what so ever. I highly recommend these headers. I have installed headers on many cars in the past, and by far, these were the easiest.

 

I have the Dynatech Supermaxx headers. They look, sound and run great! I have only compliments for Dynatech and the installer.

 

I still say Dynatech's biggest problem was a DIY problem. You need to be aware of heat sources.

 

You cannot go wrong with LG's.
Although I went with TPIS for my C5's nitrous application...

I have 6 sets in stock as well as up to 50 in my dealer net work We produce our own product by hand so we back our own product you do not have to talk to another manufacturer's if a problem arises here is a dyno sheet the car had corsa catback and no tune what so ever call me if you have any further ?
