89-18 Dodge Cummins Steed Speed T3 Exhaust Manifold

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

Includes:

• Turbo mounting hardware
• Turbo to manifold gasket
• Cylinder head to manifold gaskets

This manifold is built with a center-oriented T-3 Exhaust Flange that is pointing at a 45 degree angle downwards, the same as the stock flange on a 89-02 Dodge Cummins
: Some customers may experience turbo oil feed line clearance issues. You will have to get a new turbo feed line made with a 90 degree fitting or source a 45 degree fitting.

Wastegate port adds an additional $250 to the product price.

Other styles can be made to order for the same price, the usual lead time is 4-6 weeks for delivery.

Your satisfaction is guaranteed! If for any reason you are not happy with your Cummins manifold you can return it to us for a full refund.
This does NOT apply to manifolds ordered incorrectly. Please BE CERTAIN of the wastegate style you want before you order it. ALL SALES ARE FINAL ON MANIFOLDS ORDERED WITH GATE PORTS.
