Hey that last video is me! It always falls back on the video never doing it justice! but i can tell you it definitely was worth every penny to me! plus you can remove the "j pipes" like i did and you get a little more growl and loud at the expense of some drone :thumbsup:
And to answer your question, i would say the 2nd video from 2:42 - 2:52 like Sander82 said. you really should just hear it in person if you can!
