    MudrunnerTD the part number for the 3 inch rubber bend is P547694 and you should be able to get it through any company that sells Donaldson products if you like I can give you the number where I purchased it from

    I have the 3ltr motor. So I did this mod with the hi flow maf housing. I noticed no improvement but now I can raise my boost levels far beyond before without getting limp mode.
