    depending on size you may get a bit of power but on a newer vehicle such as yours ur just better off putting a performance one instead. or else it may run too rich, too lean, mess up ur O2 sensor and cause some engine problems. i have experienced with my car so i know what works and right now i have just two performance mufflers (BORLA) no cat or resonator. the sound i have is low deep tone and while driving it sounds almost stock but with a bit of sound just high enough the hear it, nothing annoying. with a single exhaust it may sound a bit louder.
