Since purchasing my car and planning aftermarket upgrades I knew that eventually I would want an aggressive, single-exit exhaust. After upgrades that were more about gains than aesthetic I started listening to clips online and discovered that a lot of single-exit catbacks sounded great when everything else was stock, or maybe one piece changed, but full exhaust cars with single-exit cans generally developed a nasty, metallic rasp and tearing sound.
I pretty much gave up on the single-can option but, as I was deciding between an Invidia or Dezod setup I heard a clip with the Revolution RS and full exhaust that finally sounded right to my ears. I wanted a sound that would do well in a "Pepsi Challenge" with a WRX and that's exactly what I got, paired with the JDL catless UEL header and JDL "Ultra Quiet" Over-Frontpipe. It's quite loud, to be sure, especially cold starts. But I love it.
