A manifold and up-pipe kit for the 2001-2004 FED LB7 emissions package, pairing high-sil moly cast iron with aircraft-grade 304 stainless up-pipes.

Key Features

  • High-sil moly cast iron manifold
  • Internally sleeved up-pipe bellows in aircraft-grade 304 stainless steel
  • Increased inner diameter for higher flow
  • Built-in bosses, pre-drilled and tapped 1/8 inch NPT for an EGT probe
  • Designed to lower exhaust gas temperatures and speed turbo spool-up
  • 50-state emissions legal under CARB Executive Order D-701-36
  • Raw finish

Fitment

2001-2004 GM 6.6L Duramax LB7 with the FEDERAL emissions package, and 2001 California trucks. Confirm your emissions package before ordering - the 2002-2004 California LB7 kit is a different part number.

Note: the 2001-2004 LB7 factory down-pipe does not fit aftermarket manifolds and up-pipes. Plan on an aftermarket down-pipe as part of this installation.

Note: up-pipe configuration can vary by model. Confirm yours before installation.
