RE: DL55 or EVO58
Hughes,i had the very same set up in a 88"EF yak,evo58 on a mtw pipe ,i was rite at 17.5 lbs.
great set up,LOTS of power,i was spinning a Beila 24-8 prop at 7500.never could get the mid-range throttle response like i wanted ,but i probably never got the perfect length header.
if i was to do it over again i would just buy a MVVS 58 from Pe.i think they pay more attention to assembly.
