so just recently I bought a 03 wrx with 70,000 ks. I use to drive a r32 and I new everything about them but I don't no what to start with upgrading my completely stock rexy !!

I've been told to start with a exaust system, but there are so many types and I don't no where to start looking ! I'm after 1 that's not to loud on idle but mean sounding and when I start to rev out more of a powerful sound but again not to loud .

I'm located north of the river so if any of you's have exuast shop or anything for sale can you please let me no !!
