Description

The Steed Speed Cummins ISX T6 exhaust manifold is a high-performance, one-piece automotive masterpiece designed with optimal flow in mind for Cummins ISX engines. Owners can expect faster turbo spool, lower EGTs (potentially up to 150 degrees lower than aftermarket options), higher peak boost, and reduced drive pressure. This one-piece design offers advantages such as ensuring no leaks, being easy on studs and gaskets, and not requiring retorquing under normal conditions. The manifold is CNC machined, hand-finished, and ceramic coated to ensure smooth flow and long-lasting durability. It features a T6 turbo flange and is a direct OEM replacement for Cummins Part Number 3880199, but with a T6 flange. Key features include lower EGTs, increased spool, power and fuel economy gains, and a lifetime warranty.
