Here's what I have on my 2000 legacy outback sedan...
For engine performance this is what I have... Borla header, random technology high-flow catalytic converter, stromung 2.25" catback exhaust, weapon-r intake, Perrin lightweight crank pulley, beatrush lightweight alternator pulley, agency power pitch-stop "dog bone" mount, buddy club grounding kit, xcceleration's .445 lift "hot" cams, titanium retainers, and stronger springs. I have purchased the following, but are not installed on the car... Perfect power smt6 ecu, walbro fuel pump, Wrx injectors (440cc), and custom parallel fuel rails.
For suspension... Ksport gt pro coillovers, superpro steering rack bushings, cusco front strut bar, whiteline anti-lift kit, whiteline front swaybar end links, whiteline 20mm rear swaybar, kartboy rear end links, whiteline rear adjustable lateral links, cusco rear strut bar, beatrush rear frame bar, and all remaining suspension bushings are by powerflex.
Future plans... 8psi supercharger kit, STI shortblock and run 14psi on supercharger, change over to turbo and run 18psi, big brake kit, wheels/tires, paint it all body-color black, throw on my Baja turbo hood, maybe head work and everything associated to max-out the SOHC engine.
