Do you own a 2008-2014 WRX or 2011-2014 STI?  Do you like single exit style exhausts that provide good fitment, great looks, and a more aggressive sound with minimal to no drone?  
Then here is your answer...The Invidia Racing Series Cat-Back Exhaust! It provides everything above through increased piping diameter and a much less restrictive muffler. You should also benefit from more power, more torque, better throttle response, and even reduced turbo lag in some cases.
