Out of tailpipe http://video.tinypic.com/player.php?v=2meth7r

its not the best cause its from my camera but i could never find one half decent so here ya go...

From inside the cab it sounds great... a little deeper, driving home the other day i drove right by a wall and gunned it and it sounded rad... when your on the gas hard it sounds LOUD and powerful...
