    What are the HP gains from this exhaust compared to stock? Thanks


    • The Ford Performance Active Cat-Back Exhaust w/ GT350 Lower Valance will not really give you any more horsepower over the stock exhaust, maybe 2-3 more horses. Cat-back and axle-back exhaust would be more for sound and not performance. You will want to look at the long tube headers for performance.

    Are there any plans for making a video of this exhaust system for how it sounds and is installed??


    • At this time there are no plans on adding a video for the Ford Performance Active Cat-Back Exhaust w/ GT350 Lower Valance (15-17 GT Premium). With that being said, we are constantly working to get product videos containing installation help and descriptions up for all the many items we do have in our inventory.

    will this system fit my current Stainless Power headers? I understand i will need a 3" to 2 1/2" pipe adapter.


    • As long as you get thestep-down adapter pipe yes this will work.

    i have got ford borla sport cat back with gt 350 rear valance which is similar to this , is there is a way to buy just the key that closes and opens the valves


    • Unfortunately, we do not carry just the key in this kit separately. You may be able to source that through Ford Performance directly.

      Looks and sounds amazing

      Completely changes the look of the rear end of the car. Quiet mode is a bit louder than stock, but has a much deeper growl with zero drone at highway speeds. With the butterfly valve open, the volume is increased dramatically and an even deeper note without the rasp of other active systems I've heard. There is quite a bit of drone at highways speeds, but shutting the valve obviously solves the problem. It's a pricy system, and a dealership install was more than I anticipated, but the end result is fantastic. I enjoy having the option of changing the volume and tone on demand. As a side note, be careful of the placement of the electronics. Water caused the unit to malfunction. so it needed to be reinstalled in the trunk.

      So aggresive sound!!

      If u want to be a little bit quiet, switch off. Want to be angry? Switch on!!! Not too hard to install, but it takes time about 5hours.
