Maybe these could be a replacement for Nismo headers?

 

I like everything except for the possibility of them reaching $900. I would still get them more expensive than the others, if they sold me on their quality, but if they got up that high, that would make it an even harder sale!! Just sayin...

 

Check out their website and look at the quality of their products. It speaks volumes for itself. They are truly masterpieces of automotive art. He said that the Nismo's were very flawed and that his design would address every issue all current headers for our trucks have, either great power down low and not much up top or ho hum performance down low with a good top end charge. There is no need for coating with the thickness of the SS he uses. You truly get what you pay for with these headers. F-body, Corvette and Mustang owners know they are the best hands down as well as the Mopar crowd. Like I said, I know the price seems kinda steep, but this has yet to be finalized and is still TBD. Maybe if we can sell 20-30 sets the price will come down like the DT group buy.

 

I would like to know what he thinks about the Nismo's is flawed? Has he had a set? I mean, the Nismo's have equal length primaries and a merge collector? They do amazing on the bottom and top-end, I gained 1/2 second+ with them.....Just wondering whats so very flawed

 

All the twists and turns they have to make them equal length slows the exhaust flow down and creates friction. The more twists and turns you have for a gas to follow, the more it slows down. His design I'm sure will be as close to equal length as possible while allowing smooth bends and transitions to the collector. I would like to see the inside of a Nismo collector to see if it truly is a merge collector because from what I see from pics of the outside, they aren't. Plus, they are a mid length and use smaller primaries to make up for the shorter primary lengths to promote the low end tq.

 

I along with numerous members in this part of the country have checked out the inside of the Nismo's, and yes they are a merge collector. My Nismo's gave me a lot more top-end. Not saying which will be better, I'm basically just discussing this LOL. I honestly don't think I would want my collector any larger, I love the torque, unless the longer primaries makes up for it. We will see, I remember when the DT's came out there would be arguments that they would be better then the Nismo's, but I haven't seen proof yet. Every company who wants to start making something, is going to say that the "other guys" product sucks. Hopefully they wil make some, and we can get some people runnign the same times as the Nismo's....LOL JK man. nah hopefully they wil give you even more then 1/2 second +....If they do, I will buy some, but then I wouldn't be able to sell my Nismo's for a large amount of money like I could now LOL

 

The thing about Nick is if he thought they were a good design, he wouldn't even want to bother making a new set from scratch, he could have just used a pair of Nismo's and copied them. This dude used to make all the prototypes for Kooks Custom Headers and branched out to make his own company.

 

Well, by looking at my posts and my signature, you know I am in the market for anyhting that will perform better then what I have. So if they do prove to be better then the Nismo's, then guess what would be on my truck LOL. I also think the reason the Nismo's went away, was because no one was buying them for that price (although they were better then all the other cheaper headers). Hopefully that wouldn't happen to him, this economy is rough though.

 

 

^^^^^^^I like!!! I like the extra piping LOL

 

Now are you gonna tell me you guys would pick DT, Stillen or god forbid.....Pace Setters when you could have these?

 

I'll take a set of DT Shorties all day long, off road style...........

BTW - The Nismo's and Stillen's are tested and proven so until you can prove otherwise sure I'd buy DT, Nismo & Stillen 1st.........

 

I would be willing to pay the $900 if they were available today. I currently have an order on DTs (they're backordered), but I don't see myself going through the pain of swapping out DTs for these 6 months from now.

 

Hang on to that money and cancel that order. This is going down for sure. I mean hell, I am driving my truck from south TX to NY to have the prototypes done. These things will be well worth the wait.

 

just my opinion, if i wouldn't have bought my Doug thorleys i would buy these, especially if he has branced off from KOOKS, which make the best headers known to date, i know cuz i had some on my 650rwhp mustang and they added 35rwhp. (1-3/4in primaries x 3in collectors, 4 into 1) awesome products great quality and they were slip fit connectors meaning you could install each primary tube one at a time... makes for easier install.

just sayin....

 

For upto 900.00, they should be coated.

 

Look at those pics I posted carefully..........how many hrs. of fab work do you think it takes to make those? No offense to DT, but there is an exact science to making a high performing tri-y and Nick said that they are nothing like a real tri-y header should be like. They made them that way for installation and cost savings. Not that they aren't a good product, far from it. There has never been a premier company like ARH to make something this bada*s for our trucks and now I have the opportunity to bring this to our Titan's. Don't let this slip away. These dudes will make more power than any other header ever made for the VK56 engine.

 

i can vouch for ARH craftsmanship, my shop is down the block from ARH, and i send them some of the stainless header work i need and lemme tell ya, hes the real deal- second to none. people who are in the business dont even think to question the price on a $2600.-3000. custom header job bc they come out MINT. my cuz swapped a new fuel injected 8.1 vortec (pro charged of course) into his 70 monte and just had nick build stainless headers- he spent over 12 hours just mapping his bend routes for optimal flow on a single side. he had the car for a week and did the most ridiculous fitments and welds ive ever seen... $900 is a great price in my opinion for the technology, theory incorporated and most importantly the quality of material that is used. this guy will not build or sell anything that isnt done perfectly.

 

the price on a $2600.-3000. custom header job bc they come out MINT.

That's ****ing insane. Are they made of gold??

 

I'd be interested, especially if it includes the b pipe, but like most people its going to come to how much.

 

Add me to the interest list... I just would like to see a complete long tube setup that doesn't require O2 defoulers... basically, long tubes, to single Hi-Flow cats, to Y or H pipes... I just don't understand the need for secondary rear cats just because I have a 4X4...

 

You can use single high flow cats with your Titan now. You don't need defoulers or anything with your 4x4...the only requirment is your 02 sensors need to be behind a cat, and thats going to be the same with the ARH....You don't have to do anything special for a 4x4

 

those are nice. kooks isnt that who makes alot of the nascar headers?

 

are nismos even being produced right now? ( <-- serious questions, im curious )

nope! So as much as we like to argue about the Nismo's, its really invalid, because they are NO MORE! And it will be hard to find a used set, because people like me know that currently, they are the best design and I wouldn't part with mine for anything, unless something comes along that works a bit better. I'm always in the market for something better, as long as it proves it self

 

... i thought so

 

 

^ Those are an equal length mid-length header, not a true LT header. See how the primaries are all twisted around with a bunch of odd bends? That creates friction. Any change of direction slows down exhaust flow/velocity and creates friction. If Nismo would have made them a true LT, they would flow smoother and make a lot more power than they do. Trust me, if they were the best design, he could of just copied them and made slight improvements to their existing design. As of now, they are the best design currently out there, but that doesn't mean they're the be all, end all either. This will surely change.......in the future.

 

not trying to bash in any way shape form or fashion, just curious about why the opinion was stated about the ''flawed Doug Thorley merger collector design". 4-2-1 tri-y type looks like a decent design, yet i'm no engineer or physicist but i'm always willing to learn.

I'm also a true believer in KOOKS, best on the market and you get what you pay for.




Those of you who are interested, I will sell my DTs for 500 bucks only been on the truck for a month and haven't even turned a single color.

IF AND ONLY IF ARH will make a complete LT package with an x pipe, cuz i'd like to get some 1-3/4in(primary) x 3in (collector) headers that are similar to kooks or better. don't care about jet hot coating or whatever, as long as they are stainless and thick metal... i'm good!

I know bigger collectors/primaries etc will reduce torque in a sense, but we are all looking for average hp/tq numbers not peak.

Count me in for the ARH LT headers/x pipe deal. Maybe ARH will do a kooks type slip fit collector so you can install each primary tube one at a time.

who do i have to talk to and where do i send the money to get started?!!?!? lol (seriously):teethmast

 

Just hold your horses....lol. There prolly won't be any x-pipe with these, just the headers and b-pipes/mid pipes. After the initial testing goes, we'll talk about further development of a high flowing merge y-pipe setup and maybe even a complete exhaust system front to rear. Who knows? Just have to wait and see.

 

3"?? Even cammed Titans that have 3" collectors on their headers have used "reducers" to reduce the size. I would personally lose all my interest if they went with a 3" collector design...They would probably be great if you got the stroker kit

 

It depends on the header design. Nick builds headers for all kinds of stuff, Ford, Mopar and GM trucks alike. He will not make a header that looses a lot of low end tq. With our current headers, since they are mid lengths, they are usually for fitment issues, but the power band on those is usually midrange to upper midrange and towards the top end. Short tubes are geared even more so for top end. The longer the tube length, the lower in rpm they perform best. Nismo, Stillen and DT are all mid length headers that are made to bolt up to the factory b-pipe, cutting down development time and aiding in fitment issues. That is also why they have such small primary tubes, to make up for the shorter tubes. Nick is a header making genius and I understand every principle he has told me that comes to making a good header. The collectors he uses are a true merge design with a flow spike in the middle that necks down the collector using a venturi principle to increase the scavenging effect. Then, he will possibly use a slip on reducer to get it down to 2.5".
