Had them on my 11 5.0 and it sounded great lots of compliments. After going w o/r xpipe the drone started to get to me.. It's not the worst I've heard but it's definitely noticeable.. I switched over to the gt500 axle backs and I love them. Theyre a little quieter at idle and normal driving.. Just as loud at WOT. I like the sound better personally but the hushpowers aren't bad either.
