2011 Mustang GT with Roush axle-back exhaust. Car is all stock otherwise. Medium acceleration through first with hard pulls in second and third. I'd definitely recommend this exhaust for anyone looking to wake up their 5.0 coyote mustang! Is a little loud on a cold start, but goes away after a few seconds with a tap of the throttle. For the most part no drone, but on the highway it can be a little loud a particular rpm.
