I've got my hands on a jacobs extarder exhaust brake. was aondering if anyone else was running this model on a 5.9L . I'm pretty sure it's a brake for the 8.3L Cummins, but my cousin had it on an 02' 3500 & it worked really well. the jacobs part # is 019229 the cummins part # is 3928758 & the model # is EXC 83, any info on this brake would be greatly appreciated, I'm also gonna need a compressor to run this thing that comes on at at least 65 psi & shuts off below 150 psi, any ideas???? thanks a bunch , Dusty
