Flowmaster Hushpower Exhaust Interior Review - 2011 Mustang GT 5.0
There weren't any interior videos of the hushpower axle-backs, so I made one. Unfortunately, because I shot this on a phone the sound is a bit quiet. The hushpowers are actually a good bit louder than in this video. Definitely louder than stock.
