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.
Except that’s what is actually being compared.
Of course diesels without exhaust brakes, James, retarders have squat for compression braking. It’s just a function of their design. And since all the Hd pickup diesels have had VVTs for well over a decade, it’s now just a standard feature.
Comparing a light duty class 2-3 or even class 4-5 diesel with a functional exhaust brake (Cummins at least, I’ve pulled with a LML Duramax and it was meh, better than nothing, never towed with a 6.7 Powerstroke of any flavor) is no contest.
I can roll down a 6% with a 6ton trailer behind the ole 4th Gen and basically never touch the brakes unless I want to call up a downshift, but I’m usually in manual anyways, and a new 10 speed gasser pulling my boat of about half the weight is on the hooks multiple times.
It’s not even an apples to apples comparison as the exhaust brake will win 10 times out of 9.
