st3v3..get yourself a better panel filter, the 2.0 litre auto deflector from Ford (£8). A new exhaust will not necessarily make it sound pants. Got a H&S custom job on mine from CAT back and it burbles bootifully . If you're considering a supercharger, then there may be no need to go the Bluefin route. I think the butterfly on the ST TB is 63mm, so a 65mm TB won't really give you any improvement, plus the one from Focus Central etc will not fit anyway as it's got a different mounting footprint. Think one may be in the making somewhere though
