Deviant Race Parts 01-04 GM 6.6L Duramax LB7 Intake Elbow

Factory LB7 mouthpieces are necked down and restrict flow to the turbo. DRP's Intake Elbow eliminates the restriction by increasing the diameter to a full 3". Our Mustang Chassis Dyno has verified a 25hp gain to the wheels by just adding this piece. 



  • 3" Mandrel Bent tubing
  • Slotted holes allow for easy, bolt on installation
  • Louder Turbo Whistle
  • Faster spool up
  • Dyno Proven 25hp Gains


2 out of 5 Wrenches for installation (1 wrench being easiest)
