Absolutely music to my ears for the money!!
This is absolutely hands down the best sounding Axle-Back exhaust system available for a Mustang. Then again, it’s Roush!! It is what I would expect.

Louder that thought
Seems to be a lot louder than in their video. Look good, and the Shelby is putting out 620 Hp, without much effort.
