12V T4 Manifold with the stock angled flange, no wastegate port.
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!

1 : Highest power
2 : Best economy
3 : Lowest EGTs
4 : Most durable
5 : Fastest turbo spool


  • Turbo mounting hardware
  • Turbo to manifold gasket
  • Cylinder head to manifold gaskets
  • Two 1/8" NPT ports for probes

This manifold is built with a center-oriented T-4 Exhaust Flange that is pointing at a 45 degree angle downwards, the same as the stock flange on a 89-02 Dodge Cummins.

Manufacturer's Warranty: The warranty is for as long as the original owner owns the manifold. Manifolds will be repaired or replaced at Steed Speed's discretion. The customer is responsible for shipping. When shipping warranty items contact us direct for instructions regarding return.

What material are SteedSpeed manifolds made of?
Our manifolds are cut from solid 1018 mild steel billet.

Do you provide hardware?
Yes with the second generation manifolds we provide turbo and head gaskets, turbo mounting studs, nuts and washers.

What coating do you use on your manifolds?
We use Techline coating. This coating is rated to 1700 degrees continuous use and can take short periods of up to 2000 degrees. You should be careful not to scratch it when you are installing the manifold. Satin black is our recommended coating.
