The HKS Sport appears to be a nice affordable low-key exhaust, despite being 3". I am not sure how loud/quiet it is behind a catalytic converter. Too bad HKS does not offer a 2.5" version with a resonator on the mid-pipe, but it still seems to be the most sensible exhaust available for those who want something in between the stock peashooter and an annoying cannon, since the aftermarket is mostly aimed at Hoonigans.
