Anyone gotten an aftermarket exhaust yet?

I gotta admit, that I'm finding it extremely difficult choosing an exhaust for my M4...



The youtube clips don't really do the vendors any favours, as they all sound pretty meh, but then people chime in and say that the exhausts sound very different and much better in person (which really doesn't help either! lol)



Sooooo, has anyone in Sydney changed their exhaust yet?



:help:
