pd tuning/amzperformance manifold!!

We also have custom manifolds made by Escort Racing out of Japan however those would seriously put a hurt on the "other manifolds" produced by "other" companies.
Our manifolds are made of quality 314 SS not 304. There is a HUGE difference in the quality of steel. If you look at the steel guide you will notice that the 314 is the highest next to iconel being on the cost basis. I can assure you that none of our products are generic or second hand. We offer a 3 YEAR warranty on our manifolds... No one is offering that with a bolt up manifold. NO ONE!!!
Many offer warranties with a custom manifold because its a one off meaning designed specifically for that car. Those usually are never warranted due to the fact they are race designed and tested on race cars however consumers buy them for their street cars.
I can go on and on about quality and manufacturing but I won't. I've been doing this for MANY years now and we have NEVER had any issues with our products nor customer complaints. We offer our parts at exceptional pricing.
Guess what? That one, looks just like this one in post #12 did before I had it coated:

...busting no one's *****, but this is the most copied manifold in exisitance...

the ssautochrome and the "tomei" mani and the meagan mani and this mani they're all the same copy off hks...
if they make it outta 314... and it is indeed the best steel... that's good. some are willing to pay a hair or so more for that kinda benefit. how thick is the steel btw?
also could you chime in about your intercooler pipe kits? how much and stuff... i'm tryinna find your guy's website.

The design of the manifold may seem the same until you see it up close.
There must be a reason why this style of manifold is copied... It is a relatively straight foward design and extremely functional.
Like Mitch has said up top the manifold was contrated out over a year ago to give the consumer a choice in the market that is dependable and gives them a great performance for the money they are spending.
We are coming out with several other designs for the GT28rs and the rest of the Garret GT series lineup. They will differ slightly in turbo location to accomidate the larger compressor housings. They should be ready in 2 months.
We know alot of different kits are on the market, but we want to be able to use a product we produced.
Along with the fact that we want to make sure that the fitment and quality are there on every unit.
Our customers are extremely happy with it and that is all we care about.

Structural Stability
The problem of grain boundary carbide precipitation was discussed under intergranular corrosion. This same phenomenon occurs when some stainless steels are exposed in service to temperatures of 425 to 815°C, resulting in a reduction of corrosion resistance which may be significant. If this problem is to be avoided the use of stabilised grades such as Grade 321 or low carbon "L" grades should be considered.
A further problem that some stainless steels have in high temperature applications is the formation of sigma phase. The formation of sigma phase in austenitic steels is dependent on both time and temperature and is different for each type of steel. In general Grade 304 stainless steel is practically immune to sigma phase formation, but not so those grades with higher chromium contents (Grade 310) with molybdenum (Grades 316 and 317) or with higher silicon contents (Grade 314). These grades are all prone to sigma phase formation if exposed for long periods to a temperature of about 590 to 870°C. Sigma phase embrittlement refers to the formation of a precipitate in the steel microstructure over a long period of time within this particular temperature range. The effect of the formation of this phase is to make the steel extremely brittle and failure can occur because of brittle fracture. Once the steel has become embrittled with sigma it is possible to reclaim it by heating the steel to a temperature above the sigma formation temperature range, however this is not always practical. Because sigma phase embrittlement is a serious problem with the high silicon grade 314, this is now unpopular and largely replaced by high nickel alloys or by stainless steels resistant to sigma phase embrittlement, particularly 2111HTR (UNS S30815). Grade 310 is also fairly susceptible to sigma phase formation in the temperature range 590 to 870°C, so this "heat resistant" grade may not be suitable for exposure at this comparatively low temperature range and Grade 321 is often a better choice.
this doesn't sound good for 314...

Do you have a link to where the info came from?
Again as stated many times before, we wanted to bring a product to the market that was more durable than mild or 304 SS that is widely viewed by many in this community as a cheaper and stronger alternative to the factory piece.
321 by far is the way to go.
314 in this application and the cost go hand in hand,
Every manifold that is in production for the future will be a 321 SS unit or a combo of Inconel and 321. Our very Next unit for production and ready by June will be the Inconel steel unit that we will use in our high HP shop vehicle.
We are just providing an alternative to the Ebay and SSauto units that seem to flood the market with complaints.
PD Tuning.
oh sorry didn't post the link... http://www.azom.com/details.asp?ArticleID=1175
if you guys are changing your steel grades that sounds awesom... i think it'd be worth a small price bump and people would be willing, very, to look into it.
not only do they wanna avoid supporting ssautochrome they also want some more peace of mind.
