Not sure how I missed all the negative feedback about Dynatechs but after doing some more refined searches I found way more negitive than positive.

Has anyone with these headers made a significant increase in power. I.e. dyno numbers? Track times? SOTP? Car wouldn't spin tires before, now it spins all the way through 3rd gear, etc?

Please, no header war comments or this header is better than that one.

Feedback greatly appreciated!

 

I hope you're wrong about more negative than positive. I just ordered a set. Actually, all the research I did was mainly positive. They won't get you as much HP as LG's or Kook's but $500 + for an additional 5 HP isn't worth it to me.

 

Just what was ALL the negative feedback???? They had very early minor fitment issues that were corrected. One guy had an abnormally high baseline dyno and then claimed the headers did not make any power for him. If you read the post, you will see everyone trying to explain it to him.

That system is a great system, and it's much less than a certain someones other system.

 

I just installed a set that I have had for about a year, I had them coated before installing them. The fit was outstanding, and I couldn't be happier with them. I wouldn't hesitate for a minute to buy them if I were you. I don't pay much attention to the dyno claims as far as horsepower gains with header systems that are very similar in design. Just my $.02

 

I am very satisfied with mine.

 

I am really considering buying a set myself. Most of the research that I found was mainly positive. The only thing that I found was the Kooks and LG LT's could make some more HP but for additional $$. I can't seem to find a way to justify paying ~$500 more for some extra HP. There is a GP going on at the moment for the Dynatech's with a price that looks pretty darn good.

 

The kooks and dynatechs are priced within about $50 to $100 of each other. It is the LGs that will really blow out your wallet. I again see no conclusive evidence that any of these systems provide more horsepower or torque than the other on a consistent basis. On average all will gibve you rwhp gains within 5 of each other. I liked the quality of the dynatechs and I also wanted the 32' primaries so I chose that system. Your choice of a system really depends on your current setup and where you plan to take the car in terms of mods. Once you get up into the 400s rwhp the system you choice will begin to have a noticible impact on performance.

Yea, but the Kooks are cheapo mild steel and the Dynatechs are SS!

 

[QUOTE=2KREDVert]

My Kooks are S.S., same as Dynatech and LG.

 

I have them on my 2001. Had no real fitment issues at all. I had them installed and then had the car tuned and went from 319HP/338TQ to 339HP/355TQ peak numbers. This is WITH the cats. Complete area under the curve went up. (I also have a Vararam/GHLs but those were installed prior to both Dyno runs). It also extended the curve up higher in the RPM range for the TQ. It used to start decreasing at 4200RPM now it continues climbing until 4700RPM. I can dig the dyno graph out if you want.
Average increase under the curve was around 10-12 FT/Lbs until 4000 RPM and then it climbs. At the peak point of 4700RPM it is around 25FT/Lbs more than stock (all at the wheels). At 5000RPM it is around 20FT/Lbs more and holds that pretty much till 6000RPM.
So summary... I am very pleased with the results & fitment.

True of the headers themselves, but I thought the Kooks change to carbon steel beyond the headers. The Dynatechs are 304 stainless all the way from the headers to where they bolt up to the catback system...no carbon steel at all. I could be wrong about the Kooks, but that is what I've seen posted. Both systems are great performers!

I have narrowed my searches a couple of different ways and the last one I used was, "Dynatech Results." Check it out and you will see what I'm talking about.

Equal or less than HP/TQ dyno numbers before and after install. You will even find track times that didn't change with equal conditions before and after. Afterwards, go to other brand headers and use the same search criteria and you will definately see what I'm talking about.

I'm not concerned with fitment issues with these headers. Seems that those issues were identified and corrected. Dynatech seems to have done alot of research to assure that the asthetics are on the mark.

To be honest, I could care less what the dyno numbers say. I had an LT1 that only pulled 305 HP to the wheels on a DynoJet but ran 12.20's@109 on Nittos.

Look around for cam only 11 second LS1's and see what headers they are running...? I looked and maybe I didn't look hard enough but I didn't see very many with Dynatechs.

If these positive results are anywhere to be found lets see them in this thread.

It is too late for me anywhay, I ordered the Dynatech Supermaxx system and I'm even paying to have them coated........

Lets hear more positive results. Thanks.

I forgot to mention: Alot of the positive results that I did see had Air Fuel Ratios that were beyond lean.........

 

Hi GUys,
I don't want a header war either but I would like to point out that there is more than a 5 hp difference. We are removing a set of Dynatechs next week to replace them for a dissatisfied customer.
He was not satisfied with the gains after he put a cam and head in the car so he is getting our headers.

I will keep you posted on the results.

Lou,

Had your prices for emissions legal headers been a little more in line with what the rest of the headers are selling for you would have had my buisiness and alot of others I'm sure. I can't even begin to imagine how much buisiness you lost from people that were on the fence over LG and Dynatech headers when LS1 Tech and Tom Byrne announced thier latest GP Pricing.

 

I would have bought an emissions legal set over the dynatechs if the price had been between $1400-1500 shipped. I cant wait to see the dyno results of the person who volunteered to do the LGM vs. dynatech challenge at LAPD. What ever happened with that?

 

I love mine and I put down similar numbers that LG's/kooks produce. If I had to do it again, I'd choose the dynatech's again.

 

Hi GUys,

Our emmission legal with four 02 bungs are in and ready to ship.

If Chevy would lower their price of the Corvette to the same as a Cavilier, they would sell more Corvettes too. And they surly lost Corvette sales because of the higher price but if they lost money on every sale they would not be in business very long.

I understand that there are some things in life that cost less.

Our headers are what they are. We have high quality, and features that others do not.

We tried very hard to make every inch of our header the very best that we could. I would not accept any compromises from our Manufacturer. I stipulated that our header MUST include the true race Merge Collectors. That was one point that we would not budge on even though the collectors cost much more than a standard collector.

When it came to an X pipe, Borla already had a 2 1/2" X pipe that we could have used at a much lower price, but we declined in favor of the full 3" X pipe that we incorportate in our system.

Likewise, when the decision with regard to what cats to use came up, we would not allow anything but a full 3" cat, and mandated that they be the new Metal Matrix cats because we knew from testing that if we reduced the size or construction of the cats it would compromise the performance that we wanted and the horsepower.

Plus our LG headers do offer the ability to interchange from Cats to off road for track use.

Now, as a good business man, and a dynatech dealer, not only will I sell you Supermaxx if you want them, but I will match ANY price that you can get from any dealer for the supermaxx headers. That will at least allow LG Motorsprots to provide the quality, one stop service that we try to offer.

We have always been a Dynatech dealer, infact we use to use Dynatech real Merge collectors, ( $250 each) on our hand made headers for a year and a half.

So please consider LG Motorsports even if you are interested in Supermax headers, because I will match every GP price or any sale price.

Since I am a firm believer in our product, I will not hesitate to spell out the differences when we speak on the phone. But if Price is the determining factor, we will be glad to be the company to sell them to you.

Thanks for your time, and I look forward to working with MORE of you rather than less.

While I understand that you are trying to say that your headers are somehow the Corvette of headers, your comparison doesn't come close to illustrating the difference in quality between the two headers in question. A Cavalier doesn't even perform the same function as a Corvette. If I were in the market to buy a Corvette, a Cavalier wouldn't be my alternative. In this case the two products are very similar. Much like considering an FRC as opposed to a Coupe.

Some things in life do cost. Sounds like Borla is charging you a whole lot of money to build headers to your specs or the opposite which I won't waste my time going into.

I don't appreciate you hijacking my thread in order to market your product. This seems to be the case with many of the other Dynatech threads.

The Topic of the thread is still an open and unanswered question. Is there anyone with Dynatech headers that has had positive results?

 

Nick,

I have been very happy with my DynaTechs. I have had them on the car for about a year. I did have mine SwainTech coated.

Here is my dyno graph. Notice the A/F I kept it at 12.8 to be on the safe side. I could have posted a graph with the A/F in the high 13's and had higher HP numbers but wouldn't have driven on the street that way.

 

I too considered LGs and probably would have gone that way but two things changed my mind. (1) The LGs didn't have the capability to hook up all 4 O2 sensors (at the time) and (2) The LG headers for a 99 didn't exactly bolt right up. They required a change in the Air tube which requires removing the Intake Manifold.

I can't help but wonder why the "best" headers didn't have this capability? I just thought that the LGs were made mainly for racing applications and not necessarily for the street.

One last thought of mine. I think that the Ferrari might be a better car than the Vette but it's not even close when you consider the bang for the buck. The same with the Viper. These, to me at least, are a better comparison than the one previously mentioned.

There will always be a market for the ultimate header for those who have to have the ultimate performance machine but many of us don't have the money to go satisfy all our desires which is why we drive Corvettes instead of Lamborginis or Ferraris.

Of course this is all just my opinion and I don't mean to down anyone's product or opinion.
