PPE's high-flow exhaust manifold and up-pipe kit for 2004.5-2005 GM 6.6L Duramax LLY, pairing a high-sil moly cast iron manifold with internally sleeved 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
  • Silver Ceramic Coating finish

Ceramic Coating

The ceramic coating acts as a thermal barrier and does not absorb heat as quickly as raw metal, which reduces surface temperature and thermal cycling and helps keep exhaust gas temperatures down. It also protects against moisture, road salt, oil, fuel and other corrosive chemicals.

Fitment

2004.5-2005 GM 6.6L Duramax LLY applications.

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