The BANKS exhaust brake I put on the 2001.5 worked great for the 12K+ load I towed with that truck for 14 years
There is no doubt exhaust brakes work. If you do turn it off, then back on while going down a hill. And nobody that has ever compared can say diesel, with no exhaust brake, or it not functioning, will claim gas engine does not slow more.
What nobody wants to compare is normally functioning gas engine to like sized and loaded diesel with exhaust brake.
The Cummins for some unknown reason pretty much freewheel without the exhaust brake on, where as the V8 Duramax and Powerstroke provide a degree of grade braking.
