Rear dump Exhaust Manifold for a 12 Valve Cummins.

This manifold features a turbo flange that dumps between cylinders 4 & 5. The front 4 cylinders dump into the frontmost volute of the T3 flange, and the back two cylinders dump into the rear volute. This is commonly seen on RV's, buses, and is frequently used on Ford trucks with Cummins conversions.

All Exhaust Manifold Bolts or Gaskets are sold separately.

Option for Bolts is 12 x 3944593

Option for Gaskets is 6 x 3929881

Please call in with your Engine Serial Number before ordering online so we can verify this fits your engine/application.
