Great
As a 2015 mustang gt owner with this exhaust system I can say it's fabulous! Although I have a few recommendations that roush engineers and app developers could integrate. Other exhaust companies have certain features such as location based triggers for exhaust. Having the exhaust shut or open or change to any given percentage within a certain "radius" of an address would be nice. Also having more customization other than just speed and throttle. Having an rpm customization would be great. The current graph is only based on throttle percentage and speed. Having it change according to rpm would be a fabulous addition. I hope engineers can see this and maybe do something because roush is starting to have some competition!
