Hey guys, Im new to this forum. I own a 2011 WRX and it is completely stock as of right now. I was thinking i would get a cobb accesport for my first mod. Would this be a good first mod? Also what kind of exhaust has a nice deep boxer rumble but at the same time is kinda quiet? I like the sound of the spt but i feel like they still have to much restriction as far as performance goes. Am i wrong?
