New Dodge exhaust manifold available

I am going to dyno one of these soon comparing to a ats cast piece. Both are t4 outlet, I know that the common rail manifold with a stock setup other than the manifold saw a 24 horse increase. I will keep you posted.

see now this is where comments get misleading....

Where was the 24 horse increase? Upper rpm band I presume. And show us the side by side comparison to justify these increases.
 
Thats why i said i would keep you in the loop after i dyno it. Wasn't trying to be misleading in any way shape or form.
 
I'd like to see a side by side comparison on a 12, 24 and a CR truck with like a ats cast manifold. They look sharp though.
 
I would like to know the longevity of them. I mean hanging a turbo on a piece of stainless steel has always been a problem with cracking. I think they look sweet but before buying me one I would like to hear from some that have had them for awhile.
 
seems like a whole lot of sizzle and not enough steak. Undivided flange, 4 cylinders on the one side in a small pipe, and you have to pay extra for bungs?
 
Somebody needs to do an exhaust manifold shootout with dynos to back everything up.

I've always thought that too, but a weld pipe manifold like that shouldn't be too bad.

The one I'm worried about is the one I have on my truck. The equal length header. But Hogue has been running one for a good while with a decent size turbo hanging off of it, and he's seen a lot of heat cycles at some high temps. So far, so good... we'll see. the EGT reduction w/ the header I have is worth gambling for IMO
 
All performance aside, those look the coolest out of all the ones I've seen... :D Should flow well or atleast better than a stock manifold, though I was curious about how well they would handle an S400 hanging off of it unsupported. Once again though, they look sweet, lol.
 
Anyinfo yet on the 24V one? I would love to see some results. Got cash in hand ready to buy.
 
So is anyone running one of these now? how is the spoolup & EGT's vs. stock? and power thruout the RPM range? Also I just talked to the guy who makes them. He said he should be getting his first perduction run of 20 units in about 20 days.

i think forrest was saying that you are comparing apples to oranges

hundred dollar pair of sm blk mild steel headers with thin flanges compared to this thing?

all stainless and 9/16" flange

cant really compare

don

ps - nice lookin part
 
I can see 2 major problems with this header. He won't sell many, and if he does, his phone will be very busy in about 2 months. He should have done more testing on that design.
