I have a 2012 Legacy 2.5 Premium and would like to add a dual exhaust system to the car. I want to do this from a purely cosmetic standpoint, not looking for any performance gain (a little more rumble would not hurt).
Any suggestion as to how to accomplish this as economically as possible? Rumor has it that the system from a Legacy GT will fit, is this accurate? Will installing such a system throw any CELís?
