I'm new to this site and a noob mustang owner, had to wait until the kids moved out so as not to wreck this car. I have the 2016 Ecoboost Premium with the Pony package. So far I have installed a K&N CAI and tuned with SCT standard load...looking for the Torres tune next. My next purchase is an exhaust. I am exhausted from reviewing all the youtube videos trying to get the best and pulling my (what is left) hair out listening...they all sound the same after awhile.
