I’ve never heard what you’re referring to, but could it possibly be the turbo barking that you’re hearing?

Exhaust leak?

Good morning, it almost sounds like an exhaust leak as the exhaust brake is actuating, barking?

Interesting, I've had two 6.7L trucks and not experienced either symptom. I had an 02 3500 that I installed a BD exhaust brake that was adjustable. At the max setting, it would whistle ans would bark (sudden air resistance to the turbo blades).

Do you turn on your EB every time you drive it? If not, could be build up of carbon. These EBs need use and saves brakes. I keep mine on all the time, but would turn off in ice or slippery conditions. hope this helps. Cheers, Ron
