7.3 headers....

[dietoremain]

Okay so who's running some and what kinda set ups you have? My bud has a truck goin together with a 4294R and some other goodies and he wants a set of headers bad.. I've heard about DI, Empire, and Carson having them.. what ya'll running?? let me know!

I'm still waiting for some steeda speed manifolds for the 7.3

I run DI headers.

They were part of the build 6 years ago so I have no way to compare to stock manifolds as they were never on this motor with my set-up.

They sound great....and I'm sure they help improve flow but like I said I have no way to compare to the stockers.

I'll try to find a sound clip

I wouldn't mess with them. Seems like alot of people that have had them, have had problems.

I think thats more the new ones, the old ones seem to be holding up great.

Melting? or the welds?

I have not heard much bad with them.

I didn't know Carson sold headers?

I ran DI headers here - they were awesome - but I did a lot of mods at the same time. From experience - I say they helped cool EGTs down and helped spool the turbo earlier and easier - but that is not hard data that most people want.

Every set I've ever been around either warped, melted or cracked and were replaced with stock manifolds. With that said, there are some guys running them without issue.

They seem to be a hit and miss type part. Which is unfortunate giving the price and depand. Who wants to run headers. Im waiting to see what Steed Speed does.

 

[Groomzybanshee]

I believe a lot of it has to do with the up pipes or can be fixed from warping with some added support

Steed speed would be nice but damn they are expensive. I just don't understand why 7.3 headers are flirting with the 1k mark? Why are they so expensive?

I think you are completely correct. I used a solid set of 321SS up-pipes with no provisions for movement and flex like is needed for a set of cast manifolds.

 

[TARM]

SO the solid uppipes helped prevent warping by adding support and rigidity?

 

[bad12jr]

I'd guess being all stainless the expansion rate was the same from the pedestal to the up pipes and headers.

If you keep your egt's on the gauge, you will more than likely have no issues. Back when i used to get my headers glowing over 2000* i had one issue with cracking, never with my 250/80s. That said i sold off alot of performance stuff and they didnt make their way back on the stock engine. Loved everything about them though, worth every penny

Because they have to do with a "Powerstroke diesel" For some reason that makes prices jump I havent found out why yet. LOL

What isnt expensive in this market.

 

[TARM]

How much do duramax headers run. They all seem to be in the 1K range.

Its not really apples to apples to compare to a straight 6

Steed Speed has them at 1K. but they aren't out yet
