The Jardine pipe housing would be an excellent size for a fibrosleeve. Basically, it turns your muffler into a glass pack. It takes the volume down a notch, absorbs the higher frequency angry lawn-mower sounds and makes for an awesome, very distinctive deep growl. They are definitely a head turner.
Here's some sound files for comparison. A buddy on the other site put my two sound files to a moviemaker clip and posted them.
