Check this out. According to these folks you should stick with stock diameter if you are making no other upgrades.

Exactly, you gain more from staying with stock size but going with mandrel bent pipes. Same with cold air intakes that usually only gives a faster throttle response but no real h.p. gains on small engines. Read alot of research and studies on it.
