I went with Non-Resonated CBE and a Non-Resonated Test Pipes just because I wanted a loud car LOL. I love the sound, its loud and just a tad raspy LOVE IT!!!!! But it can also be quiet. I have almost know drone at all. Took a ride all the way down to NC and never once get a headache. I chose Test Pipes over HFC because of the huge price difference and because of the few HP extra you get. I was also planning on getting my car UpRev tuned which would stop the chance of me ever getting a CEL. Hope this helps.
