Catback System

I'm looking to get a bolt-on catback system for my civic 1999 GLI Sedan (is it EK9??? or EK4).
I'm looking for something with a deep sound but not loud and looking to spend around the $550-$650 range. Something like this (http://www.nengun.com/kakimoto-racing/kakimoto-r)

Does anyone have any recommendations and also if anyone has any audio clips of what it would sound like, that would be heaps of help.

I really want a catback but don't want the really loud exhaust noise. Just enough so that its noticeable when accelerating hard. My car is manual so want it to be noticeable when changing gear. I think you guys know what i mean..
Thanks

ek1 your car is.

ue car is EK1.. same dimension as the coupes...

for ur price range... best option might be xforce syetem with twin loop muff

Thanks for clearing that up.
I was thinking of putting a pod air filter in as well. Would that affect the sound of the catback once i get it? So would it be best if i get a silencer with the catback?
No one has audio clips of their catbacks?
