Steed Speed Manifolds/Headers

[POWER Freak]

Has anyone heard anything good or bad about these yet? The website says they are currently at Fleece being tested. I ran a Steed Speed on my old Cummins and it was great so I am very curious about these but they seem like they might only be useful for extreme builds...

I just sold some stuff to Leen last week and he said they were still in testing or to be tested. but that was all as of the first of last week... not sure if any new news.

They're getting into Duramax now? Their Cummins intakes are nice pieces.

I sent Steed my up pipes about 8 months ago maybe more for him to use for mock up. This project has been going on for awhile now and I hope the results from Fleece are good. I was told if they don't show any improvement or gains over what is currently on the market he will pull the plug on the project. Fingers crossed.

Super nice Subd I hope it shows signs of improvement I'm guessing they are stainless

Updates here????

Test results are in and definitely positive results but he is redesigning again and hoping for more improvement.

I've been working on a set for a while that will be going on a large triple'ed truck soon. This is just a rough piece at this point.

I thought they did pretty for just manifolds and factory up pipes. Wonder how much more he can wring out of just the manifolds?

I put a 3rd gen t3 steed speed manifold on a 6.7 cummins with a silver bullet it out performed all the other manifolds with the same turbo/tuning/truck comb it was definitely worth the wait and money

Just how would these be any much better than what is already offered? They look exactly like Rick's.

I think it's hard to be the reliability of the cast manifolds for a street truck, and guessing there would be little if any power increase with the billet version's.

He kinda pissed me off a few years ago when I sent him my stock ones for samples, test pieces or whatever and then took months to get them back, even went to his house once when he knew I was coming and he was nowhere to be found. Only to have nothing come of it.....till now.

Will see how his pricing stacks up against what’s already out there. I know he builds great stuff but I don’t know if it’s really going to out perform what’s already on the market.
