OEM exhaust brakes, air or vacuum?
 

Hello All;
I was just wondering what activates/powers the butterfly on the exhaust brake, air or vacuum?
If compressed air, is there an onboard air tank that can be used for other things, such as airing up tires on the truck itself or ATVs?
Thanks in advance.

On the newer trucks I believe it's electrically activated and contained within the turbo. All you need is to pay the dealer about $90 to have it activated.

On '06 models, Dodge approved the Jacobs brand brake. It has a vacuum pump system that powers the brake. Is this what you're asking?

I was wondering about the trucks that came w/ the factory exhaust brake.
I didn't know about the electrically controlled ones. I thought they were either air pressure or air vacuum activated. I was hoping for air pressure.
I'm looking at updating to a 2010 and was curious.
Thanks.

The 4th gens are in the turbo.
