I am considering putting QTP cutouts on my 2008 Mustang GT Convertible. Last year I installed American Thunder exhaust and it a great change. I would like it to sound mean when I want. I would use the best kit, almost $500.00 wireless. Does anyone have this installed on a stock Mustang ? Other options I have done are 3.73 gears and cold air induction with tune. Thanks, Jim
