I am new to the impreza scene, and I just traded my 04 cavalier (junk) on a 2005 impreza RS. I am very happy with my purchase and had a simple question to ask. I am sure this may have been asked before, so sorry in advance! I am looking to upgrade my exhaust with a catback system, maybe cobb or invidia, and i was wondering will it produce the same exhaust note from a wrx as it will on a rs? I am not sure how to describe the sound, but it is distinct.
