Hi. New here and introducing myself. I used to have a classic STI import wagon many years ago (325bhp) but sadly had to sell due to family commitments. I have just returned to the subaru world but with a lesser car. Just bought a week ago a 2006 hawkeye wagon 2.0R. My questions are, what suspension options do I have (not coil overs) as it's like driving a jelly and 1 rear shock is knocking. What cat back exhaust options do I have to improve exhaust note. And finally what of these parts are interchangeable new or used with other models and specs with no modifications needed to my wagon 2.0R?  Saloon stuff? WRX stuff? Etc etc. Thanks in advance, Al.

Tein super streets or what ever they call them now are pretty good, not too hard yet a good performance upgrade.

Wotcha and welcome - nothing wrong with a bit of NA - I know the wrx cat back option will fit the Hatch but not sure about the Hawk, these guys have a specific section for NA models
