• Wehrli Custom Fab LLY 3" Y-Bridge Kit

    $699.00 $678.03

    WCFab LLY 3” 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” bridge with a heavy duty machined beadroll on the end 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” high flow intercooler pipe compliments the y-bridge to offer a full 3” tract from intercooler to engine. The 3” Y-Bridge will work in conjunction with our S400 over stock Twin Turbo Kit if you decide to upgrade in the future.


    Note: A LB7 passenger side up pipe or our 2” Stainless Up Pipe kit will need to be purchased separately to fully remove the EGR.
