More pictures of measurements. Waiting on my shop guy at this point..should have them made this week...
For ease of reference...2.84 inches is 72.xxx mm. 72mm is the size of the stock maxima tb. I will have a 77mm version as well (havnt cut that yet)
Also note: breather tubes are cut to 6 inches in length...and the last picture shows the breather on the intake pipe..intakes are cut to 6.5 inches. Shorty pipes are approximately 3.75 iirc.

I have enough cut for an initial batch of about 24 units to be ready at once...(about 18 longs, 6 shorties)
for those following the thread; the shortage mentioned few posts above is resolved. that piping is in hand as well.

^^ Good point. I was thinking of the what i thought was more common (the 09+ TB swap instead) which im pretty sure is a 77mm measurement.
the nwp tb is almost 400$ new...not too sure how many are springing for those. In any case..as the 75 tb is smaller than the 77mm intake tubing there still shouldnt be any real issue of air turbulence or loss of power (if it was the other way around id be concerned) but i have a feeling this will be a nice fit with the 75mm as well taking wall thicknesses into account.
In all fairness here i know it wont be a problem...taking this into account...
75mm=2.95276 inches
77mm=3.0315
Rather be a hair over than under...and you have to understand the natural variance tolerances in a machined piece like this...
Ppl ask for a 3 inch intake...this is the best anyone is going to get or offer for that matter

^^ What would be really cool is if you made a true 3" midpipe, with a 3" ID that way people can have the upgrade without having to tune or get a new TB. This will be especially helpful for those that have a bunch of mods but dont want to tune anything much past stock.

^^ I do have 3 inch ID pipe here as well. it WILL be offered as well at a slight premium. prices by foot are diff. I just havnt gotten around to cutting that...Im waiting to launch that slightly after recouping some funds.
Beyond this...taking it to the next level..i intend on offering as of now only in the 3 inch ID size an all in one with a maf adapter and intake as one piece (roughly 14 inches long) This will be highest tier product.

^^YeP i have limited quantity of 3 in ID....3 qty to be exact...more or less all pending; the third being you if you are interested. It ALL goes into the shop tomorrow to get made.
The 3 I.D I havnt finalized price but it will be higher. The second wave of all these (as i intend to keep offering these) will have 3L variants and a approximately 12-14 inch long 3 in ID all in one intake with a MAF housing as well. That is going to be top tier.
When you see these in hand...im sure you will be happy.
3 Inch as mentioned above is technically 76.2mm. I will have exact measurements with the digital caliper soon. its going to be close to this. There is a definite difference in size between the two sized intake tubes.

I hate to say it but. . . 6061 aluminum tubing is extremely cheap.
I can buy like 10ft of it for around $100, tube sizing in this case doesn't matter much.
Now don't get me wrong, I don't mind people making a profit, just seems a "bit" high to me. Welding doesn't cost much either.
I've just been doing a bunch of research on this mid-pipe deal, seems like every custom mid-pipe anyone ever offered on here cost an arm + leg. Not sure why. . .
I can make a full mid-pipe out of 6061 w/ MAF and everything incorporated, for roughly $30-40 total and that includes paint with thermal coating. That same midpipe can be made of 7075 aluminum for roughly $70-80. Just saying
That said, I may be interested in your full 3" kit (MAF incorporated) if the price was right. Most likely I'll end up making my own.

^^Best to PM someone something like this.
There is nothing wrong with 6061 aluminum for this purpose. These intakes are thick and sturdy (albeit stronger than they need to be)
As far as pricing; as you touched upon it...I am going on the history of pricing for similar products....Although prices arent set in stone it may vary by the time they become ready. I envision having complete kits available as well in the future ( maf adapter, couplers, clamps and midpipe to make it easy (ier) for the community.
With all that said; Pieces were dropped off at the shop today. i can add that poweder coating is in the works!

I was just speaking my mind...
I've simply been doing some research. Look, custom mid-pipes that are nice have shown to be right around $100 over time on this site.
But then again the old Berk/Frankencar midpipes or at least one of those used to run like $50 IIRC. So it's reasonable to ask then, if we can possibly get such a midpipe again for similar price.
At the same time, I realize it all depends in the manufacturing, and bigger companies like Berk were probably able to manufacture those for dirt cheap.
As for 6061 aluminum, of course it's perfectly fine, and I would never question it's structural strength.
No, 6061 is good for this. What I was saying, is that it's fairly inexpensive.
Also, if you ever felt what 6061 feels like on a hot engine after a long drive, you would see where the difference is between these alloys. 6061 will get hot while 7075 and the like will never get hot, because it has the fastest heat dissipation.

7075 (aerospace grade) will be considered for future batches once i look more into it heat dissipation properties. As of now from multiple sources, 6061 is plenty strong for this purpose and heat soak isnt a large factor. Stainless steel may be the best way to go here but its not cost effective/heavy.
As of now; my pricing is looking to be ~ 50 shipped for the shorties and 70 for the regular sized mid pipe.. These are all for the 72mm intakes.
the 77mm will only be available in ~7 inch and approximately 12-14 inch sizes. The larger 12-14in (haven't determined actual sizes yet) being maf integrated. Prices for those still to be determined.
For anyone with any further concerns to the prices? is more than welcome and encouraged to PM me if desired.
Update:
Info from the web to put this to rest..perhaps
Aem uses 6061 from what i can see and from their site
"The rate at which air travels through the inlet path under open throttle, when one is asking the engine for maximum power, minimizes the effect of material heat soak, regardless of the material"
Injen
The Injen Technology cold air intake system is a high-performance, dyno-proven system made of CNC mandrel bent 6061 T-6 aluminum alloy.
These are Identical to what i have here. T6 grade 6061 Aluminum....dot dot . .
I am NOT a big company; merely an individual that had put a lot of time into this recently.

^^ That pricing looks pretty fair really.
I've been looking into it more, and realizing that with having to pay a welder, prices do go up, and the problem is with smaller batches being way more expensive.
AEM/Injen/K&N and most other intakes made of aluminum do use 6061 alloy, you're correct.
Which makes the price of those "professional" intakes even more retarded. Like I said 6061 is perfectly good for this, especially with a nice thermal coating on it. It's just that 7075 is way better, good racing intercoolers are made of 7075 instead of 6061, just as an example.
That said, 7075 is WAY more expensive and not very weldable. So I don't know if it's good to use here. I brought it up because I happen to have a velocity stack made of 7075 which is awesome and is NEVER even slightly warm on a hot engine.
Anyway, I'm glad we got the conversation going about all this.
Believe me, I'm in no way trying to stymie what you're doing here dude I'm just looking into it a bunch like you have. Please keep us updated on that full 3" kit (w/ MAF incorporated)!

^D Stillwell You have a PM.
To everyone else here and involved can i get some feedback on if Satin Black is a safe bet for powdercoat. Are you guys really looking for other colors? Stay tuned; should hear back from the shop perhaps today/tomorrow.

Just got call from Shop. All pieces are welded...Pending the powder coats. I dont want to make the decision to have them all powder coated one color or something and not make you guys happy hehehe. lemmme know if its desired in black
09-16-2014, 12:11 PM

^ Sounds good. In the end...i think it may be a safe bet of the initial batch of 22 pieces maybe i powder coat about half of them..perhaps leave 10 bare for anyone wishing to polish? or spray paint or leave it as is. fair to assume i hope.

I pick up the bares (non powdered) tomorrow. The powder coated ones i ordered will take extra few days 
I ordered 12 to be powdered ( all 3 qty of the 3 in intake, 5 qty of the 6.5 inch regular sized mid pipes, and 4 wty of the shorties)
NEVERTHELESS tomorrow i will have them in hand. If i only had a maf adapter in hand...gonna have to drill holes in the one i have as it doesnt line up. Once thats done; i will have pics posted in bay as well.

I will finalize prices ( even a reduced introductory price) but a range has been mentioned a few places in the thread) tomorrow once i myself see the finished product. Powder coated ones will take few extra days. As a bonus im working on a bulk purchase of couplers/clamps as well....still up in the air tho.

^^Its a proven design to my knowledge. Are there better setups? sizes (i say ofcourse)
I have no funds for a dyno or other tests. Anyone willing to do this perhaps in socal can have one for half price.
