I'm surprised that the axle back roush exhaust is mellow around town until you step on it. I had roush axle backs on a 14 GT premium I just traded in for a 16. The Roush I had, wish I could remember the model, were extremely aggressive, all the time. I loved it. My family could hear me from half a mile coming home. On the highway, drone was unending at any speed. As much as I enjoyed that, for the 16, I am thinking borla street cat backs, magnate flow street cats, or flow master street cats.
Does the resignator in the 15-16 calm them down from the 10-14 mustangs that the roush is tamed? Did any of you use roush axle backs and install an x pipe?
