I think one reason it is so difficult to improve on is
that Audi required the 4KQ to be just as fast or
faster Vs the Coupe GT of the same vintage for
marketing reasons. They designed a special 2-piece
cast/tubular heaser system and a very good exhaust
system to get 5+ HP more from the otherwise identical
engine in the Coupe GT to overcome the additional
weight of the AWD and keep the 4KQ as fast or faster
Vs the Coupe GT of the day. They put a lot of extra
development work and expense into the 4KQ exaust for
this reason.
