I have been looking for a solution for my Syncro Westfalia with it's TDI
and my LT 4x4 with the 2.4L I6 for an exhaust brake.  I have been in
contact with several vendors of these systems and all tell me that won't
work and are really not recommend for Volkswagen because they have
hydraulic lifters and the back pressure will cause the valves to rise and
then hit a piston...

Besides running massive brakes, is there
anything else I can do to get some engine braking?  Perhaps a
butterfly valve on the intake system along with a blow off valve to ensure
there isn't massive turbo spike?

I was sort of looking for that
nice braking sound going down a hill...
