Any input as to whether or not they help flow? I haven't heard of any breakage problems on the 3G's and the manifold doesn't look that different from stock. Just wondering if I need to add it to my BomB list.

 

Big differance than stock.#4&5 on the stock run together and out one hole.On the ATS the 3 rear goes to the back port on the turbo flange and the front 3 go to the front of the flange.A lot better flow over stock!I had a pic of a cut away but can't find no more maybe someone else has the pic?

 

would one of these for a second gen work on a 1st gen

 

Is that ATS already drilled and tapped for the pyro?
Also the list two. One for around $450, and one for around $600

 

more $$$ version is high temp coated

 

The manifold is not pre tapped, but there is a sort of reinforced raised area for the pyro to be drilled and tapped into. It is located on the top of the manifold. I am not sure of any temp drops, but after I installed the manifold I think I had a 50 degree drop. After the Scotty III, 4 inch exhaust, and the manifold the temps dropped total 125-175. Since my EGT's measured from my pyro are not caliberated it is just a rough estimate. But the manifold is a good thing, especially what katoiler stated about the porting for the exhaust gas.

 

I have never seen one of these manafolds, but I have seen pictures of it.
It seems to be a two piece job with something like a slipjoint to allow for expansion. Sounds like it would be prone to leaks.

 

Nope no leaks at all!!Same as on the big trucks,Caterpillers and so on.

 

With the amount of hammering I had to do on mine to get it to fit together (should have done the oven/freezer deal)... it's NEVER leaking

 

I only used the freezer and a torch, just to heat up the female end enough for the frozen part to slide on to. I still had to take a mallet to it, but only a few hits. It was my first major addition to my truck. I just wish I would of had it coated before I put it on.
