Universal glass-fiber bottle used as mid-pipe resonator and as mufflers before each tail pipes:



Vibrant Ultra Quiet Resonator will replace Universal glass-fiber bottle used as resonator (thanks to mtechnik2 and Saltysalt !):



Cherry Bomb bottle glasspack will replace Universal glass-fiber bottle used as mufflers (both, one before each tail pipe):



Any comments about changing brand/model/config?
Always thinking on deeper sound at any RPM, less loud/drone on cruise.

Lesson learned: if you dislike a louder straight pipe with a glass-fiber bottle chamber sound, then, forget the "pops"
