Either the Enya or Magnum will fly fine on a pipe....
Pass on the LA

Hi!
Any modern twostroke engine will benefit from a pipe.....it's more a question of how much the improvement will be!
You will see an improvement even on your OS LA engine!

An engine with aggressive timing with benefit most from a tuned pipe. However, any engine will get some gains from a tuned pipe. Not as much as others but every engine will gain something. For an engine like the LA it's just not economical to pursue.
