Profab 3" Short Y Bridge 04.5-05 LLY GM 6.6L Duramax

This black powder coated 3″ bridge will flow what you need on the LLY!

This allows you more flexibility & includes a 1/8″ port for NOS or a boost gauge.

Our bridge is opened up inside and a flow diverter cast into the back for better flow. Comes powder coated black. Off Road Only!

Use with our 3″ Boost Tube.

You will also need a way to disable the exhaust feed up to the EGR cooler. We recommend a set of our performance up pipes. We also have caps available, or you can weld your riser shut.

To make installation easier, you may add our lower stud kit above.

Please Note: Installing this Bridge is not for the faint of heart!
