So as I stated in a different post I just bought my first Subaru. It's a 2011 sti. And so far I'm loving it! My only complaint other than the fuel mileage......is that it don't sound like a Subaru should. It's all stock and I want the Subaru growl you can kinda hear it with the stock exhaust but you can tell she wants to be louder. I like the quad tips too. So I need some options for awesome sounding exhausts that ain't gonna cost me a arm and a leg. I'd prefer to stay around or under 600 bucks for a cat back. Thanks in advance for any input.
