Hey to all im new here, i own a VT executive serie 1 and would like to make some modifications to it.. Im thinking about doing the following

Platinum plugs
10mm leads
ss inductions growler kit
2.5 catback exhaust (lukey or redback)
mace engenering manifold insulator 25mm
mace engenering plenum spacer 12mm
pacemaker extractors
slotted rotors

can you give feed back on what mods are worth doing and what other mods i could possibly also do..
