Awsome! I would be in heaven if I can muster 400rwhp @ 7psi. I'm not worried about cats and have been running with them off for quite a while, will we be able to tune for no cats in this case? I can't recall what kinda FM you guys are looken at, any insight?
Keep up the great job, I'm looking at your kit very seriously!

But the thing is, thats what the collector is for, its to combine all three cylinders into one, making it "One" exhaust pulse so to speak.
But yes, equal length manifolds help spool time. also exhaust velocity is determined by heat, thats why stainless steel has been dubbed the best exhaust material. Manifolds like "Greddy or Ultimate Racing," (Mild Steel) won't retain as much heat as a Stainless steel manifold like, ours or power enterprise. That is unless they pay for a ceramic coating or some other form of heat coating.

My 2 cents.

What gauge, grade of stainless is going to be used?

Turbular stainless steel manifolds are great for full-race applications that see a minimum amount of on-time, but for a turbocharged daily driver I would never use it. This is why we went with a HEAVY gauge steel as opposed to a thin stainless.

In my opinion it's always better to have a stainless header, in fact they flow better, better heat retention (good for exhaust scaveging) look better etc.

this is getting interesting. i have ALWAYS heard that stainless steel turbo manifolds were never good for street cars. i've seen a great deal of stainless manifolds that have cracked on turbo hondas and dsms....and these manifolds from reputable companies like Hytech, Rev Hard, and Kooks.

Typical 1010 carbon (mild) steel conducts 219% more heat per foot than do the types of stainless steel we use in header fabrication. By contrast, quite a bit more heat stays inside the stainless header tubes and does not get passed into the surrounding air. By not allowing the contraction of the cooling gases as they flow down the tubes, more exhaust velocity is retained which promotes better scavenging at the collector. This retention of velocity increases the overall header efficiency.

However, SS is considered to be the best material for manifold making, therefore making it the most expensive. That could be a reason people knock it. But take in consideration the most powerful street cars almost always use Stainless Manifolds
-Skylines
-Supras
-RX7s
-Viper TTs
-Vette TTs
The list goes on, but there is a reason behind it, and if you read above you can get a small example of why it's used on High HP applications.

ok, but you still haven't disclosed what grade or gauge stainless you are using. according to the link you provided for Burns Stainless 304 is good for naturally aspirated setups:
304 is the most inexpensive and available stainless in the 300 series. It is suitable for normally-aspirated header applications, and has been successfully used by many racing teams. It does not have the high temperature fatigue resistance that 321 does, but is considerably less costly and much more available. Most 304 tubing these days has the dual designation of 304/304L.

Stainless is a great material to use, without a doubt. However, given the type of power levels one will realistically achieve with a Z engine, and the relative length of the manifold, I don't think stainless is the absolute essential material in this case. Certainly makes things far more expensive. I would argue probably the best material to use for a street car would be cast iron, though it also gets expensive to make and difficult for most smaller scale manufacturers to do well.
The kit does sound interesting though, and something we might be interested in offering customers, but would love to know the exact specs of the stainless steel being used.

. The exact specs will be released later.

I definitely wouldn't suggest having any turbo kit with a stock exhaust, any exhaust out there like the apexi, fujitsubo, amuse all should be good to at least 400WHP. However, a custom 3'' Turbo exhuast will yield more power and slightly different boost patterns (faster spooling) then any N/A exhaust.
