I have the s type on my 5.0
I have since stopped using my stereo and a/c, the sound is that awesome and it's adddictive
But as Borla says, the sound in the cabin when cruising on the highway is practically non-existent. While granny driving, it is there, but in no way obnoxious. But when you hammer it, it is pretty intense. I guess it depends on your taste.
Im glad I spent the extra for borla because I was worried about how loud it would be inside while driving like a respectable member of society, but that's not an issue.
I wish I could hear the ATAK, because now I think maybe I should have gotten that system. It also seems as though the sound has mellowed a bit since I put them on about 500 miles ago.
