SVTFORME2 replaced his stock resonator with a Vibrant Resonator and the car sounds really good.
Andy W. replaced his stock resonator with an Edelbrock and it sounded really good, too.
Borla - like stock, but louder. Puuuurs at WOT.
Bassani - Screams. Loud and raspy. I had to add an Edelbrock to tone it down.
Can't speak for any others since I have not heard any of them 1sthand.
