Not to complicate matters, but both Soul and Fabspeed sell twin pipes with unique designs that are different than the stock twin pipes. So, you would assume there are differences in the sounds each make and that those would all sound different than the single pipe outlet. Here is an interesting thread that might help. As yours will come stock with PSE, there may be minimal difference in sound. I added the dual tips because in the 1960s-1970s when I formed whatever gear-head prejudices I now have, dual exhaust pipes where THE thing to have. We are what we are.
