5.0L V8 power has long been the cornerstone of the Mustang legacy. Ford has once again evolved the platform with its 2015 GT Mustang, bringing power up to 435hp / 400lb-ft from the 2014 model's 420hp / 390lb-ft. The 2015 ROUSH Stage 2 Mustang takes this system and adds an abundance of performance enhancements, including an all-new racing inspired front fascia and rear wing, high flow upper and lower front grilles, "ROUSH" badging and graphics, a newly-design ROUSH wheel with ultra high performance Cooper RS3 tires, and more. The 2015 ROUSH Stage 2 Mustang also features the innovative ROUSH Activ8™ exhaust system (optional) with quad tips. The system allows for the driver to easily change the sound level of the exhaust. Other optional components include a 6-speed shifter ball, hood scoop, side graphics, hood graphics, reverse sensing system, quarter window scoops to name a few. Source: ROUSH
