sti HKS hi power exhaust
My 2006 STI. Good catless Exhaust sound, however, if you are looking for louder Exhaust do not get the hks hi power catback, there are two resonators that quiet it down slightly.

HKS Hi Power Exhaust WRX vs stock
For all you shopping for an Exhaust a nice comparison HKS Hi Power Exhaust vs stock. Same car / camera. Low rumble at low revs and fades out to the sound of the boxer engine/turbo.
