wow.. your going to get ALOT of answers here...
i had .. (now on the girl friends shee).. fmf stts and they are a good overall pipe..
they have pretty good power down low.. and pull to the top pretty good..
so if your looking for a pretty good low a better mid and an alright top.. the stts are pretty good
but you will find there are a lot of "over all" powered pipes around
But what sort of power are you after? like low mid or top?
toomeys t5s are another pipe like the stts also
