About this product
Description
3" high-flow Y-bridge for the 2001-2004 LB7 Duramax, built for custom S300 or S400 single turbo installs rather than as a factory replacement. It bolts to the OEM intake runners with a 3" bead-roll inlet, a 14-gauge aluminum neck and a TIG-welded billet center section and flanges, and comes gloss black powder coated.
Includes the MAP sensor bung, bracket and seal, a 1/8" NPT accessory port, 3" silicone boot and stainless T-bolt clamps, new O-ring flange seals and an FPRV block-off kit for clearance to the fuel distribution block. Minimum T4 pedestal height is 5" with an S300 and 6" with an S400. Bridge only; the cold side pipe is not included.
