QUESTIONS & ANSWERS

Ask a Question
  • Will this Y-bridge work with factory intercooler pipe?

    Yes you can use stock intercooler tube or and aftermarket one also.

  • Will this y bridge work with the LLY s400 kit if I decide to buy the rest of the kit later on ?

    They use a lb7 style bridge on s400 install, this would not work good

  • Will this work with a sinister diesel egr delete intake tube? I need a y bridge the factory one that blows out and I’m wondering if this will work with the sinister diesel full egr delete that I did on my 2004 lly Duramax. Thanks

    The Sinister EGR Delete will work with it, the HSP Y bridge will replace the blue sinister intake tube, but you will still need to use the sinister hardware.

    Yes it does come with all hardware needed to install

    Do this will work with: Stock, AFE, or S&B mouthpieces or also the LBZ Mouthpiece (stock or aftermarket)

  • I have a banks intercooler and pipes that are 3 inches. Can I get a boot that connects your Y bridge to banks 3 inch pipe?

    Yes Just include a note at checkout for 3" coupler and we can make sure that you get the correct one.
