Factory Exhaust Brake
#21
I have had problems with mine. I have 15,338 miles on my truck, and the exhaust brake goes in and out on its own. I took it to the stealership and they told me they could not duplicate the problem. WTF. It cuts out a few times between 2500 and 1300 rpm, and makes a wastegate sound when it shuts off. It shuts off all together at 1300 RPM.
About the only surprise mine has given me is on wet pavement with the tow haul mode on running empty. With a light tap of the brakes coming into a corner, I've had it try to break the rear tires loose more than once as it downshifted. A minor adjustment on my part fixed that. On dry pavement and in tow/haul it reels it in rather quickly. Not to mention it's fun seeing people look around wondering where the noise is coming from. I've startled more than one driver in traffic with it.
