Perfect note for my 5.0L

Reviewed By Paul B (Waukesha, WI) Reviewed for a 2015 Ford F-150 —8/23/2016 7:24 PM

It's a bit noisy at first until the muffler settles in but now she hums. It's not too loud on the highway either and there is no drone effect like the Flowmaster's. 70-75 MPH seems to be the sweet spot!!! Great American made product!!
