I have had my 2014 GC Limited 4x2 for three months now, 7000 miles, one DEF refill at 5000, averaging 30.8 mpg. My question is, has anyone added the exhaust brake kit from Chrysler to their jeep yet, part # 82211189, or added and after market engine brake? If so, what have been the results?
why would you want an engine brake on a lil JGC? I've only heard of those being used by the 2500/3500 and up when they're hauling heavy loads and have to go down steep grades...
The vario-vane turbo also acts like an engine brake, too. I suppose if you are towing lots of stuff DOWNHILL, it might be worth it to go aftermarket, though.
