This one piece, CNC machined automotive masterpiece was designed with optimal flow in mind.
Your engine will get faster spool, lower EGT’s, better fuel economy and much better durability than anything else currently on the market for this application.
These come with a T6 turbo flange.
As with all Steed Speed manifolds it is CNC machined and hand-finished and ceramic coated for smooth flow and durability.
There are many T6 manifold options on the market for the ISX, but a one piece design is an industry exclusive for this application. While the 3 piece design has its merits, 1 piece eliminates any chance of leaks at the joints and just looks pretty damn cool.
