Just got smitten by the new 2015 WRX ...have recently driven a 2010 WRX and am excited at the prospect of a 15 .Couple of questions from the brain trust...do all WRX have a loud exhaust,the one I drove was 2 yrs old... may be music to your ears but was a little loud.Also do you have to buy the summer tires and then get some real snows instead of all seasons?
