Roush Active Exhaust Upgrade Kit (15-17 Mustang GT, EcoBoost)

Roush Active Exhaust Upgrade Kit. You already know that the Roush Quad Tip Passive Axle-Back Exhaust will add an aggressive, raspy growl to the sound of your Mustang's exhaust. But, do you sometimes feel that you are missing out because you didn't opt for the Roush Active Exhaust instead? Well don't worry because now you can convert your Passive Exhaust to an Active Exhaust with a Roush Active Exhaust Upgrade Kit.

Total Control. Take total control of the volume and performance of your GT or EcoBoost Mustang with a Roush Active Exhaust Upgrade Kit. Roush's proprietary Active Exhaust system ties directly into your Mustang's powertrain control module, opening and closing the mufflers valving based on throttle position.

Four Distinct Exhaust Sounds. The ROUSH Active Exhaust System includes a center console mounted selector knob that allows you to easily switch between four different sound modes on the fly. Choose from Touring, Sport, Track, and Custom.

• Touring. The Touring mode closes the mufflers valves completely keeping the exhaust volume to an absolute minimum.
• Sport. The Sport mode keeps the exhaust quiet during normal driving conditions. Accelerator position and vehicle speed are used to determine valve position, opening up under acceleration for a more aggressive sounding ride.
• Track. The Track mode is wide-open. This mode keeps the exhaust tailpipe valves fully open at all times and doesn't restrict the raw sound of your Mustang. This mode is intended for track use and is not legal for street use.
• Custom. The Custom mode lets you create a custom sound map with the included WiFi OBD2 interface and ROUSH iOS application to personalize the exhaust sound to your own tastes. With the app you gain full control over the position of the valves based on vehicle speed, rpm and accelerator position. Download the free ROUSH Active Exhaust App for iOS - Here
