Help with exhaust

I've never purchased an aftermarket exhaust system or slip on so my knowledge on exhaust is minimal.  I've got an 06 1000RR and I'vd decided I want a slip on for the bike but what I want is a pipe thats similar in size to the stock pipe, shines like chrome, and is louder and deeper than my stock pipe but not so loud it gets the attention of the police.  Oh yeah and inexpensive.
