2015-2017 Mustang ROUSH GT Performance Pac - Level 2
Transformative ***** Review by David from Chicago
I recently had this kit installed by the local Ford dealer on my 2017 Mustang GT with Performance Package. It really made a significant difference in seat-of-the pants acceleration. The exhaust note is far more aggressive than the stock pipes and sounds awesome at high RPM. I use 93 octane gas but it may not be necessary for daily commuter driving.
A great value.
