That's awesome of you to post that for us. I don't run across many 4.6L's that I personally install so I would use any help I could getI promise you that you'll love how it sounds. I'll get some up this weekend. Ill probably have to use my phone and make a video so I'm not sure how it will sound. The sound reminds me of my 96 Trans am I had when the exhuast was stock but a couple notches louder.
