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.

how would the method of molding the metal effect performance?

look up mandrel bending. Pipes stay perfectly round in bends where as stock pipes are flattened and or rippled in the bends. Stock pipes have air flow restrictions due to that.
