Hello all... First post here so forgive me if I **ck anything up.. I have had my Vaquero for a couple years '16 model. I ordered Freedom Black Duals yesterday with a Power Commander V, and an amp with new speakers. Anyone covered this already, what am I looking at for MPG and or performance gains? Other things I added are highway pegs, taller windscreen, passenger floor boards, mustang 2-up seat. I've been very happy with the bike. With the lack of dual black exhaust my options were limited to just this..
