I've got the original Apexi WS on my car. I like that it's not very loud unless you're stomping on the throttle. My only complaint is that it hangs very low. I'm not sure if it's the same with the WS 2 though.
I might get a lip kit so that will be ok. not sure yet though. I just got my suspension and brake lines so I have to get them put in and situated. goin for about a 2.5"-3" drop
i have magnaflow exhaust, like the way it sounds. it also hangs very low, not the mufflers but the actual piping near the axle (at least for the dual exhaust version). it's louder than WS, but far from obnoxious
