Maybe this is a numbers game about "most". But for sure the Boeing B-17s,
B-29s, Consolidated B-24s and a number of other bombers were all
turbo-supercharged radials with, of necessity, exhaust manifolds. The
Lockheed P-38 is the only fighter I know of to be TSC'd. Many of the
American fighters used Allison or Merlin supercharged (only) V-12s w/short
stacks, (all angled aft). The same is true for the Bf-109 except w/an
inverted Daimler Benz motor.
The Fw.190 used a radial engine with a pressure cowl which required, like
many (if not most) other fast radials, a collective exhaust manifold.
But "the most" tips in your favor with the Mitsubishi A6M Zero. Although the
later models had collective manifolds, more than 10,000 were built with
short stacks, (all angled aft).
So endith the lesson in trivia.

And, further, most aircraft engines, at least the WWII variety, had short
pipes because of weight (a primary concern for aircraft), and not for
additional thrust, as some commenters have previously mentioned. If thrust
were a consideration, the pipes would be angled directly rearward, not down,
or in all directions, as with radials.
