Cummins Steed Speed T4 & T6 Exhaust Manifolds in Stock!

[Bobcat698]

We now offer the Steed Speed Exhaust manifolds!

The only manifold available to give a substantial gain in power and fuel economy.
Not cheap cast and not weak tubular. This is the finest fully CNC machined billet turbo manifold on the planet.
Easily outperforms every other manifold available.

Engine dyno testing shows a 30HP gain over other "3 piece" manifolds!
This manifold performs as well as the other "3 piece" manifolds with the high-flow center section available from certain vendors, but it provides it with a lower backpressure!
We run this manifold on our 3.0 Puller, Black Ice, with GREAT results!



We have 2 of the T6 straight flange manifolds in stock as well as a T4 stock angle manifold.

For the T4, click here.

T6, click here.

Do you have any straight flange t4?

[Bobcat698]

No we don't, sorry.

The website says they cannot be flipped over. How come?

He will build a straight angle flange so you don't have to flip it.

I would have to rebuild my twins piping with a straight flange.

Clearance with the oil cooler. I can have you one made with the flange facing upwards though, the same as if you were to flip a 3 piece manifold over.

I thought that too. But I think I could clock the housings to match the straight flange.
