DynoMax Bullet Mufflers

Hey everyone,
Sorry to say but im sick of my Flowmaster Super 40's. Nearly all muscle cars have some sort of flowmaster and they dont have the best flow rates either. Instead im going with a new x-pipe w/ cutout system. Im also looking at the DynoMax Bullet mufflers. If anyone has used them please let me know. Also i still want to listen to the stereo in my car so i dont want it "open header" loud. Thanks
