Idealy I'd like to tune up my engine to W140 specs. Considering mine was made around 1998 I'd say the internals are going to be identical or better to anything in a W140. No .97x engines came with a trap ox
AFAIK, my car doesn't have one though it still has that restrictive looking pipe in its place.
I don't know why the .97x info was in the W124 service set
