Exhaust similar to G35

I'm looking for an exhaust for a 2000 Impreza 2.5 RS coupe, and wanted something that sounds like an Infiniti G35. For those of you that haven't had the pleasure of hearing one, at about 0-2000 Rpm it's really deep and throaty, then it starts to get a little higher pitched. Also, its loud, but not obnoxiously loud. Whatever exhaust I end up getting I also want low-end performance gain, without too much top end loss.

What would you guys suggest?

You can't just buy an exhaust and have your car sound like another one. Get a full exhaust and it's gonna sound good, but it'll sound like your engine. The same reason a WRX sounds like a WRX, an M3 like an M3, a Supra like a Supra, etc. Your car will sound like a 2.5RS with an exhaust. This isn't necessarily a bad thing though. Just know it won't sound like a G35.
