Exhaust Question for Ralliart

I have a 06 lancer ralliart. Im new to the whole import car world and not really familiar with the exhaust and what to get. Just use to the regular V8 truck and slappin a flowmaster on it. IM CURIOUS to what i should put on my car. I want Just a nice cat back system thats going to sound good. Not too loud. i dont wanna have that annoying sound i hear all around town that all these civics have that just sound like crap. So any help with what and where i can buy something. LINKS, brands and any other info would be great. THANKS
