2011 335xi e90 exhaust recommendations?

Hey guys this is my first post, hope I put this in the right section! I recently purchased a 2011 335xi with the m package and m power kits. It is an awesome car, but i wish it was a little louder. I've been looking at the Bmw PE exhaust, but was thinking i would rather have something cat-back. Just wondering what you guys would recommend that would fit my car. Thanks
