what about the hushpower mufflers?

From: http://blog.latemodelrestoration.com...le-comparison/
These numbers are on a 2013, but I'd imagine they'd be close or the same on a 2011.





I've read that Hushpower is supposed to be louder than the American Thunder mufflers.

2012 here with GT500 mufflers, 3" HT cat back and BBK cat deletes. I had stock, then muffler delete, muffler delete/3'' and gt500/3''.

The car with no cats and GT500's wins hands down.
