it's all lies, there's no drone,only at idle speeds 0-50 (if you put straight pipes like I did)driving like a granny, I can put some noise clips up if you like but you tube will have plenty. the only problem I found is on a standard tune it just sounds like a straight thru on a stock 6 until you give it WOT with a big psssshhhhhh. I like the burble it gives though I guess I'm just used to it already after a week might have to get rid of the other muffler. I did it myself ($50/metre) but it's the lowest part of my car now so it scrapes all the time.
