2010 Scion xB
I have read that both muffler have different tones to them. What are the differences in sound between the two? Thinking of just having one muffler welded on for now and possibly adding a second, because not having a dual exhaust on the forester is nearly criminal. Was looking at either the Borla Pro XS or the Magnaflow Universal Mufflers. Any input on awakening the engine a little bit?
