Hey just wondering if anyone has been running a BAE Operations SS header on any of their daily driven trucks out there? Been about two years now since they hit the market and was just checking to see if there are any issues found with them on a daily driven truck before I shell out the money for one? Planning on putting it on a 91 D350 5-spd since I have found the manifold to be cracked. It is siting for the winter since it 2wd so just checking to see whats out there have a BD pulse flow on my pull truck but I always up to trying something new to get more mpg's!!

 

$1,000 isn't worth the small increase you MIGHT see. Even the ATS and BD manifolds at almost $500 are getting to be pricey for the small gains you see.

 

If it holds up to the heat I can handle $1000. I am after more than just mpgs. I am always looking at the performance side of any bolt on usually before what my mpgs are going to do. it should increase flow and balance it across the banks. Spool should be instant! Should also get a scavenging affect as headers do on a gasser. N the thousand bucks yeh very pricey well worth it if you dont have to worry about cracking. And plus it hard to put a price on something thats shiney under the hood!!

 

So the aftermarket manifolds that are half the price and even most stock manifolds don't hold up to the heat? Hell, I still run my original STOCK manifold that I sprayed with high temp. Rust-o-leum 3 years ago. Not a single crack or any warping present and the paint is hasn't even flaked or blistered. The 3-piece aftermarket manifolds also have a scavenging effect. They're actually called pulse manifolds.

And performance wise... There are plenty of 12v motors running around with over 400hp running the stock manifold with maybe as little as a gasket-matched port job or completely stock. And just food for thought, aftermarket manifolds don't give much of a gain over a stock manifold. Depending on the particular setup, I'd say 25-30hp at most which, in a diesel, isn't much.

Spool... That all depends. What size turbo? What size injectors? Hang a larger turbo on the manifold and say goodbye to "instant spool-up."

To each his own but I see the same benefits in a 3-piece for nearly half the price as opposed to an equal length tube header for $1,000. For me, I can easily put a price on something that shiny that doesn't have any more performance gains over an aftermarket or ported and polished stock manifold. That's a no brainer.

 

That is why I started this thread because I want to see if others have opinions on the bae header. I know what I can gain on a 3-piece manifold I have a BD Pulse manifold on one of my trucks already. All I am trying to find out if there is more to gain yet with the BAE. If I have a stock turbo with a better flowin (balanced flow) manifold it will spool faster compared to stock mainfold and stock turbo.

 

The problem with stock manifold is they shrink and warp. SS is a better option but the new Steed Speed manifolds look like a piece of art.

 

I agree. Which is why I used the phrase "most stock manifolds." Although, the manifold on mine hasn't warped since day 1. When I pulled it 3 years ago when doing a head gasket, it bolted right back in place without a problem and has no cracks whatsoever. It has even seen it's share of fairly heavy towing for the majority of its life before I took possession of it.

I would also buy a Steed manifold when the time comes. Somewhat pricey but not near $1,000.

 

Best thing about the Steed is you can get T3, T4, or T6 mounting flanges.
