The human ear is very bad at locating deep sounds. That's why sirens etc. have a rather high pitch. But even then, sitting in a car they are hard to locate.
Louder and deeper pipes will not help you in traffic, the only thing that will help is changing your driving style (since you cannot change other people's riding styles). Just as you need experience to judge the correct corner entry speed, you will need experience to "read" traffic, i.e. anticipate the behaviour of other drivers. And just as with corners the solution until you gain that experince (my guess is 20-30.000km) is to err on the side of safety: don't ride with too large or too little a speed difference relative to other traffic, don't ride where other people can swerve into you (ride next to the hood of the car next to you, not next to the trunk).
Back to slip-ons: the arrows are the best compromise in terms of sound and performance to me. The Akrapovics sound a bit nicer, but I find them to be quite a bit too long - and of the course the price is ridulous. Most other slip-ons are said to have too much of a negative performance impact. I would go with the Arrows.
