Which exhaust sounds the best?

Just creating this post as a feeler for what would be the exhaust I am looking for. My 2005 STI is full bolt on and makes 375 whp. I have a 3 inch invidia catted downpipe with a Tomei catback bolted up. Don’t get me wrong, I love the turbo whistle from the Tomei when pulling out and giving it some light throttle, but the tone is really raspy. I want a more clean tone to the rumble, a more pure rumble if you will, without sacrificing so much volume. I love how loud the Tomei is, and I don’t want to sacrifice the volume to upgrade the tone. Anyways, I was just trying to pick your guys brains to see what the best setup is for the best sounding exhaust for a GD STI.
