My S muffler has been modified similar to the Pedro or Fister style. This, in addition to Fabspeed secondary cat bypass pipes, yields a throaty exhaust note (think GT3), without drone or resonance. In addition, because the bypass pipes are welded above the center line of the muffler, you don't see them once the bumper cover is re-attached. I personally don't like the looks of the PSE with it's big pipes showing in the middle. The aftermarket mufflers I've heard either don't sound that much different from stock or are really poor sounding; I can't say if I've heard the FVD, offhand.

Poor picture, but you get the idea.
