The LLY 3 Inch Y-Bridge Kit is an upgraded high flow intake kit for the 2004.5-2005 Duramax. The factory Y-bridge is a poorly designed two piece bridge that is prone to blowing apart under boost and creating poor drivability and excessive smoke. This is a one piece fabricated 3 Inch bridge with a heavy duty machined bead roll on the inlet so the pipe cannot deform when the t-bolt clamp is tightened. This kit allows you to remove the EGR system for race use only. A 3 Inch high flow inter cooler pipe compliments the y-bridge to offer a full 3 Inch tract from inter cooler to the engine. The 3 Inch Y-Bridge (Bridge only, not the inter cooler pipe) will work in conjunction with our S400 over stock Twin Turbo Kit if you decide to upgrade in the future.
