if you ask an opinionated question your not going to get a direct answer.
paul turners, given you have mids, are great low end pipes and i love them
dg pipes ive never owned and i frequently hear dg being called the "dollar general" of exhaust
boyesen reed valves are also a mystery to me, but ive owned vf2 and had nothing to complain about.
in about another few post some one will say "what kind of riding do you do"
and you will probably be unsure of a classification of riding style.
if you got the parts mix and match, find a combo to suite you. other wise my opinion will be vf2 with paul turners
o and ya, jetting is sensitive. you may of may not need to rejet. use your knowledge of the machine
