2014 Flowmaster American Thunder
 

I've been driving my 2014 GT for a little over a month with the Flowmaster American Thunder axle back mufflers that came on the car when I bought it.

I like the aggressive sound, but it's too much for my personal taste. Anyone tried the 60 series flowmasters?

In the meantime, I'd be interested in swapping the flowmasters for a stock set of mufflers. Anyone in the St. Louis area?
