More info on Dynatech Headers
Since I'm in the market for headers I have been comparing the Kooks, LGM, and Dynatech products. Since little is known about the Dynatech headers I sent an email to Dynatech asking to confirm or accurately represent their product based on the statement made by LGM. Here is their response:
**************************************** **************************************** ***********
We are aware of LG's comments. As long as we've been building headers we have never taken the position of talking down a competitor or spreading false claims against their product. Our philosophy has been to let our service and products speak for themselves. In the end, the customers decide who wins. That being said, enough people have commented about LG's post that it warrants response in the way of facts. We've pasted in the LG post and responded in blue. (EDIT: response is in bold)
Hi Guys,
There has been a header released that looks very similar to our LG Pro Long Tube headers. I just want to point out the specific differences and what these differences mean. I hope this information helps to clear the questions. I am flattered that there is a header company that picked our design as the the one to copy, but they only went 80% of the way to a complete well tuned system.
Thanks for taking the time to read this. First of all, we did not copy LG's design. We have never had a set of their headers in our building to our knowledge. Our involvement with building C-5 headers started a couple years ago when we started building headers for FLP. Basically, FLP sent us a header and asked us to build it for them. This header is a medium length design with welded elbows making the turn from primary tube to the collector located at the start of the tunnel. We feel their header is the best ceramic coated, mild steel version on the market. It has some nice features we've codeveloped with them and it's fairly priced. While we were producing FLP's C-5 headers we began production on our own line of Supermaxx truck and SUV header systems. The success of the Supermaxx truck line was immediate and we concluded adding high performance cars to the line made sense from a marketing standpoint. We decided to begin with the C-5. We had several goals in mind before we began the design process. Obviously, we wanted it to be made from stainless steel-a defining feature for the Supermaxx line. We wanted to eliminate the long elbows used in our FLP style to help control internal production tolerances. We wanted a design with different features from the FLP version so the customer has a choice of coated mild steel (FLP) or stainless steel (Dynatech). We wanted to incorporate ODB-II compliant cat's in the system. We wanted an end-user price that was affordable. We wanted a complete, no hassle, bolt-on system that delivered all of those things and had good overall performance.
The design process started full bore when we acquired a C-5 from a local resident, Bob Bean. Bob graciously loaned us his car for around 8 weeks beginning last fall. Bob is not an employee of this Company. He can be contacted at judgeroylt1@aol.com. We took his car apart and reassembled it more times than we can count. We dyno tested his car several times during the development process at *****'s Carb and Dyno. We began the design process by locating the cat's in the tunnel where they needed to be, then moving forward towards the cylinder head. This process defined the maximum length of primary tube we could get in the car, yet still use ODB-II compliant cat's. During the design process we modeled the entire C-5 exhaust tunnel and mounting points with our digital coordinate measuring system and loaded it into our solid-modeling CAD station for future quality control purposes. This is a difficult and time consuming process, but it is necessary for accurate fixturing and quality control procedures. This process allows us to measure any point on any C-5 system we manufacture and know how it will fit in the car, without having to get a car back in the building to double check it.
As mentioned, the initial design process was around 8 weeks. It takes an additional 4 weeks to write the bills of material, quality control manuals and procedures, inspection procedures, installation instructions, etc. Copying someone else's design, although quicker to initial production, is the wrong strategy and not something we did in this case. There is no way we could risk copying another design, not knowing where the problem fit areas exist, where the tightest tolerances exist, whether the piece we would be copying actually fit, etc. We have learned this the hard way over the years when producing headers for other companies to their specifications. When dealing with the run sizes we produce and the investment associated with the inventory it would make no sense to stake that much money on another company's design. Any real manufacturing company understands this.
1) Collector: The LG Headers have a true Race Style Merge collectors, where the imitators have a heavy Cast steel basic collector that connects to to the rest of the system using a large 4 bolt flange that will reduce ground clearance significantly.
LG headers do not have race style merge collectors. We manufacture thousands of true, racing style merge collectors. Generally, they are not practical for computer controlled cars because of the difficulty getting them to seal 100%. By necessity, they are a slip-on design and therefore are prone to leakage. We do not use them in our system for that reason. We air pressure check every Supermaxx system we sell to 10 psi. A design incorporating a true merge collector would not pass this leak test. We used to sell true merge collectors to LG back in 2002. They experienced first hand the difficulty getting them to seal 100%.
Our headers do not incorporate a heavy cast collector. The collector is not cast at all. It is formed the same way we form every other collector for every other header we manufacture. It starts life as a piece of 3" x .065" stainless tubing and is pressed and crimped into shape. We have under development a cast collector version. This version was on display at the SEMA show, however it still has many months of durability testing to go through before it could ever be put into production. Ultimately, the cast version could have some unique benefits when compared to a formed collector, but we still have a lot of dyno and road miles to go through before concluding it is durable enough for our needs. It is apparent that LG has never seen one of our production C-5 headers because we've never sold one with a cast collector.
We are very pleased with our unique, ball and socket 4 bolt connection flange. To date, we have not had a single complaint with ground clearance. The ball and socket design, coupled with our sintered metal donut gasket makes installation much easier for the consumer.
2) Pipe diameter: The LG Pro Long Tubes have full 3" diameter pipes compared to the reduced size of 2 1/2" of the other brand.
That is correct and that is how we designed our system. Our target customer from design day 1 was the C-5 owner performing mild modifications (550 hp or less). If we see demand get big enough in the 600hp+ community we can easily make a 3" system. We make them every day on the racing side of our business.
2.1) Cats: The LG headers use full 3 " Metal Matrix cats where the other brand uses 3" in and 2 1/2 " out. the CFM flow of our cats is about 200 cfm greater than the reduced diameter cats. The reduced diameter cats flow 396cfm and our full 3" Random Metal Matrix cats flow 590cfm. Big difference.
Our PowerCats are 300 cells/square inch and are purpose built to be compatible with ODB-II vehicles. Again, making a larger version is possible if the high horsepower consumer dictates the need to us. We prefer the 2 1/2 outlets so we have no problems with light up times on the average vehicle.
3) X pipe: The LG headers have a full 3 " X pipe that leads into a full 3" mid/rear pipe. I would never down size our LG headers to a 2 1/2" X pipe or rear pipes, so I cannot see how it could help.
We designed our system to have the best combination of features for the investment. Most cars will either have the stock rear section (2 1/2") or a common aftermarket rear section (most of these on the market are 2 1/2"). We wanted our system to bolt in the stock location with no hassles or problems. Building a 3" section is no problem if the high horsepower market is large enough. We already build 3" and 3 1/2" x-pipes in production, but did not feel the 550 or less horsepower car needed the extra volume at the expense of torque.
4) Ground Clearance: The LG Headers have very good ground clearance due to the clamp style that we use. The other brand has at least 3/4" less with their clamps.
Clamp style is not the limiting factor for ground clearance. The lowest point for our entire system is on the passenger side header in the starter and oil pan area. We routed the tubes in such a way as to provide adequate starter and oil pan clearance. This point becomes the lowest in the system. The four bolt clamp's lowest point is in fact higher in the car that the primary tube point mentioned previously. Perhaps LG has never measured our system's ground clearance.
5) Bell housing mounting tabs: The LG mounting tabs are very strong and are welded to more than one tube for extra strength and long lasting duty. The tabs on the other brand are only but welded to one spot, just like the old FLP headers, which would break off very easily. This is because the mfg of these headers, Dynatech, also made the headers for FLP
In fact, our mounting system consists of 3 brackets (1 welded to each header and one floating). The brackets welded to the header are attached with 2 one inch long welds to a bracket formed specifically to the tube shape. The third bracket floats to allow for quick, easy installation without wrenching the headers and/or preloading them. Perhaps LG has never seen the actual mounting system we designed and use.
6) Weight: Last but not least, the LG Pro Long Tubes are 28 lbs lighter than the LG Look alike headers. That means that, on a typical cam and head you will have to make 5 hp more just to offset the extra weight of the headers. I doubt that you would like to carry a 28# chunck of lead with you in these cars, so why add that weight for no good reason.
Our system weight details are as follows: headers are 35#, cat's total 7#, interim tubes total 4.5#, x-pipe is 10.5#, all hardware and gaskets total 6.0#. The total system weight is 63#. We do not know what the LG headers weigh. Our headers are built with .065" stainless steel tubing. We do have the capabilities to build ultra light headers (we do for sprint cars now). We will go down to .035" wall in some cases, but there is no way we could use this for an application like a C-5. It would not hold up more than a couple of hours. Even if we did manufacture the header out of the .035" tubing, the weight savings would still not come close to the 28lbs. claimed by LG. Perhaps they've never weighed our system.
7) Price: The LG Pro Long Tube headers are a bit more expensive, but the combined features and performance of our headers provides much "Added Value". Plus the LG PRo Long Tubes have a "Life time" Limited Warranty for the original owner.
Our system is $1495 complete with metal cat's. We do not sell a version that does not include our metal matrix PowerCats. As stated in our original goals we wanted a complete system that was priced fairly-not just highly priced because the customer owned a Corvette. We doubt highly that our quality takes a back seat to anyone, including the system manufactured by Borla and sold by LG.
8) Service: LG Motorsports is here for you, to answer any questions. We don't rely on internet resellers with a Computer, a 2 car garage and a pair of "Fluffy Bunny slippers" to answer your questions. We are here for you and any issues you have with our headers.
Dynatech has been building headers since 1991. Our corporation has been involved with racing since 1983. We have three divisions committed to building the best products for the racing and high performance industry: AFCO Racing Products (www.afcoracing.com) , Dynatech (www.DynatechHeaders.com) , and US Brake (www.USBrake.com). In addition, we have a couple of web sites devoted exclusively to servicing the racing and high performance community: http://www.RPMNet.com and http://www.4m.net. One of the services we offer to the high performance community is our Racer Page on the RPMNet.com site. We currently have 4,050 racers and enthusiasts who have created a web page detailing and showing off their cars and/or team. These web pages are hosted and maintained by us for free. All of these sites are designed and maintained in-house as part of our sales ,marketing, and customer service group. We are not part time racers trying to sell headers and parts.
Our products are available through the best high performance distributors nation wide. Customers such as Jeg's, Summit, Motorstate Distributing, Afco Racing Products, Finish Line Performance, MTI, RK Sport, Mid-America, Etc. We don't believe any of our distributors qualify as "2 car garage and a pair of fluffy bunny slippers" whatever that means. Perhaps LG does not know who any of those distributors are.
9) HORSEPOWER!!! We have the Horsepower, and the Torque. No guessing. We will be using these headers, along with 5 other teams, in the World Challenge series this season. Teams could have bought any header they wanted, but they bought LG PRO Long Tubes after dyno testing other brands.
We have not tested the Borla/LG system. We designed ours to meet several objectives, horsepower and torque obviously parts of the equation. We're very pleased with the results.
It's unfortunate that we have to devote time to unproductive efforts like shooting down false claims from a competitor. As stated earlier, we prefer to let our products and service speak for themselves. Besides you Brian, several people have written us questioning the voracity of the LG claims. Yours finally was enough that we felt a response was necessary. We hope we have addressed the major points to your satisfaction. Sorry for the lengthy response, but there was a lot of misinformation to address.
If you have further questions please let us know.
Thanks for the inquiry,

Re: More info on Dynatech Headers (1badvr4)
I wish we had some dyno results. I also wish we knew how hard the installation is, compared to others. Interesting reading, thanks for posting it. I have yet to decide which I am going with, but some dyno results and installation instructions could easily sway me to the Dynatechs.

Re: More info on Dynatech Headers (vettenuts)
I have read on another forum where one Z06 owner had MTI replace his TPIS headers with Dynatech headers. He gained 6rwhp & 11 rwtq. However his car not stock by far so I cannot give an apples to apples comparison here.
I was dead set on buying the set of LG headers w/cats (along with some other things). I sent a request asking a few questions about the header setup and wanted a quote on the complete out the door pkg with new O2 sensors. Lou never responded to my emails over a 15-day period while in the meantime he was spending several hours each day bragging about Tuner Shootout results. After I saw him spending more time boasting about how second rate his competitors products (headers/cam/etc) are while neglecting his potential customer base I decided to take my business elsewhere.
Overall I do feel the LG has an excellent product and that cannot be disputed, but I am not partial to they way LG is currently doing business.
I have decided to buy the Dynatech headers based on how Dynatech's customer service has handled my requests for more information.
My vette will be in the shop in for a tranny/converter upgrade in the upcoming week. After I get a few miles on it I plan on doing a baseline dyno. Then I plan to install headers and go back for some dyno tuning. I can post my results when I get them over the next 2 to 3 weeks.

Re: More info on Dynatech Headers (bgood)
:cool:
bgood, thanks for sharing. I'm impressed that Dynatech took the time to answer the points raised in the LGM thread. I was curious about the 2.5" collector size, the collector being cast, and, especially, the weight issue. I agree with Dynatech's approach since I have a slightly modded C5. I've learned that the larger primaries and collectors will HURT the scavenging performance of a header and provide LESS upper mid-range (read "useable') torque. I could use a set of headers with 1-5/8" primaries since I don't have high-flow heads, cam, and LS-6 intake (yet :)), but the Dynatechs are close enough. Plus, I sent them an e-mail and they said they aren't considering 1-5/8" primaries. I was impressed by their response time (customer service, and I haven't even bought from them yet). I'm still waiting for LGM to respond to my inquiry :(
Guess I'll just have to build the engine to fit the headers :D
Dynatech, you're my #1 pick now. Thanks so much for taking the time to explain the 2.5" collector issue (I thought I was right...bigger ain't better when it comes to engine headers) and updating us on all the other issues!!! Now if they just had a less expensive x-pipe for "off-road" installs!!!!
:cheers:
bgood, thanks for sharing. I'm impressed that Dynatech took the time to answer the points raised in the LGM thread. I was curious about the 2.5" collector size, the collector being cast, and, especially, the weight issue. I agree with Dynatech's approach since I have a slightly modded C5. I've learned that the larger primaries and collectors will HURT the scavenging performance of a header and provide LESS upper mid-range (read "useable') torque. I could use a set of headers with 1-5/8" primaries since I don't have high-flow heads, cam, and LS-6 intake (yet :)), but the Dynatechs are close enough. Plus, I sent them an e-mail and they said they aren't considering 1-5/8" primaries. I was impressed by their response time (customer service, and I haven't even bought from them yet). I'm still waiting for LGM to respond to my inquiry :(

They have been nothing but superb with customer service. I've bugged them with lots of questions and they just keep answering them, quickly!

I think the Dynatechs response was absolutely outstanding. FWIW, when I spoke with a local tuner last week they recommended the Dynatech headers over the LG based on Bang For The Buck.

I like the performance I achieved from the Dynatech headers, and they look good too.
See for yourself.

Thanks for posting the instructions, how was the installation? How about the power? Did you get any errors as mentioned in the instructions?

I'm going to try the driver's side from the top since I can only get the car on jack stands. I won't be getting dyno numbers since the wife has put the kybosh on spending. :eek: I'm happy to be getting anything. :D

Re: More info on Dynatech Headers (DsC5)
One other observation, it appears they include all the gaskets and hardware required so you need only open the boxes and go.
Good luck with your installation, waiting to hear your thoughts on the car afterwards.

Re: More info on Dynatech Headers (bgood)
I've never posted anything about LG's attack method of marketing their headers, but it's one of the main reasons I did NOT buy their product. And trust me, I came very close as I still feel they make a very nice product. I understand everyone out there is trying to make a buck, but I just think they rode the edge a little too close on spreading the false claims about competetors such as Kook's or even these guys.
Thanks for posting the info above. It makes me even more glad I went with someone else..

WOW! Thanks for doing all of our due diligence for us! :thumbs: Their response was excellent , and I am defintely impressed! I'd love to see some dyno numbers!! :cheers: I know this is subjective and its better to hear in person, but can anyone comment on sound/volume of this setup, with any catback, or more preferably with Stingers?
