  • Does it drone?

  • @comedian376 It depends mine does not but I know somebody that has shorty headers and his does. Now when I just had the stock manifolds no it didn't, it would actually quiet down after you got up to speed.

  • Heres what inside the cab sounds like

  • How do you like the bb tune, and does the muffles "rap"

  • @noprobjim1 I love my tune, have no complaints about black bear. Not sure what you mean about rap. If your talking about it pop under acceleration then no, but reving it does pop higher up in rpm.
