Good used Exhaust brake that came off of a 06 with a G56. The shifter controller was cut and spliced at one time but cant see it installed. It will need 2 ECU pins that will need to be purchased from Cummins as well as a new belt. Will fit 03 to 06 common rails.

Here are the instructions for it if you might have questions.

700 shipped.

How well does it compare to say the 6.7 factory exhaust brake?
 
I had one on my 07 5.9. I think it felt and acted about the same as factory brake on a 6.7. The switch was noisy and annoying on mine. IIRC, I bought my kit new from Snedge for $900, but that was probably around 2010.
 
Yea I got ya I have everything just my brake will stay shut if I turn it on
