Hi. New member and Mustang lover for over 30 years! Proud owner of a '13 GT, 6spd with Track Pack... love this car! Have also owned '69 "R" code Mach, '79 coupe, '87 GT, & '98 models. The '13 is by far my favorite (although the '69 was a labor of love). Looking into exhaust options to enhance the "tone" of the car, but not be too obnoxious. Like the Borla options so far. Will add the K&N cold air intake as well. Figure the two will boost HP to about 450HP. Any feedback from members here is greatly appreciated. Thanks!
