EB itself works great. Just got back from a 500 mile trip with numerous long steep downhill grades. Some have stated that the 6.7L EGT's run hot and if I am not down shifting enough on hills then its possible the high EGT's would crack or warp the exhaust manifold.
On a gasser an exhaust manifold leak causes deep drone sounds or backfiring. On a diesel with exhaust brake a leak would cause a high pitched squeal? No such noise if EB is off or otherwise disengaged.
