WHHHHAAAATTTTT??????

I think he just forgot to add that full exhaust mode is also selectable as the exhaust brake in auto mode is always on and available.

You can turn off auto mode as well.

I use mine in full exhaust mode when towing, just tap the brake and let it do its thing. I even flip it on sometimes just driving around empty.

The EBs work great on all 3 and all 3 are great trucks. Check them all out and buy what you like. I went with the Dodge Cummins because of the proven drivetrain and the the fact I could get the Dodge for about $10,000 less than the other two. I see you are in Temple City; check out Browning Dodge in Norco, they sell a lot of Dodge Cummins trucks (that is if you decide to go Dodge)

Hi... I have a 2016 dodge with factory installed ex brake and love it. I use it a lot in the co., ca, and wy mountains. Save on the truck and the trailer brakes. I did not use it much on a recent trip to Nashville, Tn.. Jim2007...

My previous diesel (1994 Dodge Ram 3500 CTD dually) had the Jacobs RamBrake installed. It was great when towing the fifth wheel at a GCW of 21,180 lbs. over the Continental Divide, the Cascades, and the Sierras. It was even nice when just driving around town, or when hauling 35 bales of hay.
My current truck does not have an exhaust brake. I miss it. But, I don't miss it enough to spend the $1000 or more to have one installed!
However, if we were to get rid of the motorhome and get a toyhauler (not likely), that would change

These guys are right about the turbo brakes. All very similar across the 3 models now.
The one main difference on the market right now, if an exhaust brake isn't enough to blow your hair back, Pacbtake offers an aftermarket engine retarder that works in conjunction with the exhaust brake. Supposed to double the braking power. It sounds pretty sweet if you're towing heavy in the mountains a lot.

It is part of the turbo and should be used continuously to keep it from sticking.

well, no an exhaust brake is usually installed seperate from the turbo. every one I've seen is downstream of the turbo. yes, the turbo can vary the vains to provide some additional restriction, but an exhaust brake is completely differnent.

And I've never heard it should be used continously to avoid sticking.

and no, it is NOT the same on all three mfg. similar performance, yes, but the same absolutely NOT.

To clarify, I'm talking about NEW trucks. They all use a VGT for ex brake operation. That means the turbo itself acts as the EB. There is nothing down line like the units PacBrake or any of the other aftermarket companies were making for older, non-VGT equiped diesel engines.
Also, the EB needs to be used reularly in a VGT because the vanes will stick otherwise.
Frankly, I prefer the older system.

You need to do a little research on turbo's and exhaust brakes.

"An exhaust brake is a means of slowing a diesel engine by closing off the exhaust path from the engine, causing the exhaust gases to be compressed in the exhaust manifold, and in the cylinder."

This can be done with a variable turbo or an external butterfly. It doesn't matter how the exhaust is closed off just as long as it is closed off.

All of the exhaust brakes on Ram/Ford/GM are part of the turbo. There isn't a OEM exhaust brake that isn't.

The Dodge 5.9L started with a DIO (dealer installed option) exhaust brake that was first controlled by a mechanical switch and later the ECM and attached after the turbo. Originally they were on manual transmissions only and became DIO's for auto's in 2006 and OEM with 2007.5 with the 6.7L.

Yes they should be used often to allow the vanes to fully travel to reduce soot buildup. I'm not sure about Ford/GM but Ram does have programming that moves the vanes at startup; however, the best thing is to use them.
