its really personal preference. i think the hks hi-power/carbon-ti does the job done. my bro had the hi-power and it sounded great and worked well.
it really depends on what ur looking for. many people get the aps turboback and like it.the stromung or scoobysport exhausts sound clean,and somewhat look stock. its all up to u because any of these exhausts will fix that problem u have now.
