I put a Steed Speed manifold on my C-15 a couple years ago and so far, it’s been good. No cracking or broken studs. Even has kept its color half decent

[@mikenicholson2548]

Just bought the whole setup. I haven't put on yet but it looks awesome

[@mikenicholson2548]

Finally i will be ordering one with turbo and all the parts. My 570 needs a major upgrade looks looks perfect

QUESTION WHEN WILL they get around making a manifold for 12.7 Detroit. Another question will this manifold crack with the block i guess flex or heat and cold cycle???

[@taylor11089]

I tried getting them to make me a couple of Manifolds for Cat C-12’s, they weren’t interested. Also wanted them to make me a couple for the Cummins ISM as well.
But I get what you are saying, the Detroit S60 12.7L is a extremely popular motor and there would be A LOT of Demand for them.

Do you have a manifold/turbo kits for a 2008 ser.#46868230 Cummins ISL 400 in a newmar RV? tks

[@adielcerriteno1990]

Do they make these for a 21 X15? Mine is deleted I need something like this. Or will the ISX manifolds fit too

[@wesadams7560]

Don't hold me to it. But I'm almost certain they are all the same blocks/ exhaust bolt holes the same.
