Looking into buying a 3 piece exh. manifold and wondering if there any real advantages to it other than not shrinking. Are the egts the same or spoolup quicker? I know these are the manufactors claims, but wondering if you are seeing it in real driving conditions. Thanks Tim

Spoolup with a bigger turbine housing is a little quicker.<br>I have it cause it looks cool! <br><br>If you buy one, post and I'll give you some time saving hints for installation.<br><br>--Justin

Does tha ATS manifold flow more than the stock one?<br><br>I'm still running the OEM unit. I haven't melted it yet.

Justin, what kind of tips do you have for me? I just ordered one from piers as well as the steering bearing and bracket kit. Piers really does have good customer service. Tim

From what I've heard it flows about 13% better than stock.

not if you have a stock turbo and turbine housing.

Tips for installation.
These manifolds can be a real b---- to install or they can be somewhat cooperative.

1. Have an extra set of hands around.
2. Match the existing manifold bolt holes with the new manifold.
3. Make sure the new manifold is true, if not bang rap it on the a flat surface (like concrete floor) to straighten.
4. Just start the bolts at one end and adjust manifold as you install. By adjusting I mean taking a 6 lb beater and &quot;convincing&quot; it into position, you might use a 1/2&quot; long extension to convince the rear of the manifold to line up perfectly. (these 3 piece manifolds do not adjust with your hands, there pretty tight)
5. Take your time.
6. You might want to get an extra Allen wrench/hex key and cut about half the stock off the usable end off (to fit into the middle top two bolts)
7. Buy a socket also with this Hex key size.
8. New manifold gaskets (might as well).
9. You will need to use the existing studs from your manifold (so have channel locks to remove and reinstall)
10. Anti seize is good to apply to the studs upon reinstallation.
11. Your going to have to manipulate the provided bracket to secure to your coolant lines.

Hmmmmmmmmmm good question.<br><br>I would guess it helps when the turbine housing cross sectional area (cm^2) has the same cross sectional area as the outlet of the ATS Manifold.<br><br>you could try a PDR40<br><br> ;D ;D ;D

Dieselfreak, Do you feel it will benefit the flow to port match the ATS manifold to my PDR40 inlet? I dont even know how close they will match stock, when I get the manifold Thursday I will check and post the results. Tim

Tim<br>[/quote]<br><br>Personaly, I feel the only benefit to porting the ATS Manifold to match the exhaust ports, and the turbine housing is having the satisfaction of knowing that you did it.

The DC Ex. Manifold is another example of DC cutting corners to save money. <br><br>The N-14 Cummins that I drive interstate has this kind of Ex. manifold on it so yeah, junk the stocker and get the ATS You won't be sorry!<br>
