They are both very similar and good exhausts. I have heard the Perrin and I have the nameless on my car and they both sound more or less the same. I chose the Nameless because it was a lot cheaper since it is just an axleback and I didn't see any benefit to replacing the midpipe. I'll save my money for headers/front pipe combination where the real power is. The build quality on the axleback is really incredible, it is like a work of art. The tips are the perfect size and offset and really made the back end of the car look a lot better.
