I have a 95 model with a 540 big bore kit on it with a stk silencer . My question if I change it to say a FMF will it make the bike louder? any more power? will I have to re-jet if I do this? Now it has a Ty Davis front pipe with a Ty Davis 4.2 Gal tank and stk rear silencer! Anyone recomend a aftermarket silencer?
