First thing, the 4 model years of 2000 to 2003 Imprezas make up 2 different body styles. 2000-01 is the previous "GC" body style (actual GF for wagons) and 02-03 is the "new age" or "bugeye" GD body. Big difference there. The GD body is larger, more solid, stiff, and with better fit and finish, but weighs about 400 pounds more.
Except that the GD's have the WRX turbo model, the 2.5L NA drivetrains are mostly the same. The 2.2L was discontinued after the 01 year. It is largely considered to have been the more durable engine, but had less power than the 2.5L NA (which are very torquey BTW).
Avoid any and all "Phase 1" DOHC 2.5L NA engines (98-99 years), and look for the "Phase 2" SOHC ones. The DOHCs had less low-end torque and were prone to headgasket failure.
Boxers are really only hard to work on when it comes to replacing the spark plugs. This isn't too difficult in the 2.5L NA's with the SOHC, but is a double-bitch and a half on the WRX's. Otherwise, the pertinent stuff is all right in front of you, either on top or on the bottom.
What's your price range?
Eli, I'm not sure if my car has the exhaust you're referring to. I have a custom combo of an Invidia bellmouth DP and race pipe mated to a Prodrive muffler. It's a little quieter than most aftermarket exhausts you see, comparable to a Mustang with flows on it, but very bassy and has a sweet roar at WOT. The tip is not your typical ricer fart can either, but a polished stainless steel rolled-edge oval, very comparable to what you might see on many late-model Mercedes.

I had a Prodrive resonated centre and a 3" pipe to 4" exit rear box and I loved the throbbing sound under WOT and the scream at high RPM. It actually idle'd rather quietly in this combo, and oddly the wagon wore the 4" pretty well.
Not the best pic of the can, but then you can see it isn't dominating the rear end.
