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.

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.

For people that already bought the Ford Performance cat-back exhaust w/gt350 valance, are they gonna sell a upgrade with just mufflers and the active exhaust switch, kinda sucks to force to buy the complete system all over again


is this just as loud as the actuall gt 350


  • With the Ford Performance Active Cat-Back Exhaust w/ GT350 Lower Valance installed it will not be as loud as the actual Gt350 due to the motor difference.


Helpful (0)

Why is this called an ACTIVE exhaust? Is it user adjustable?


  • The Ford Performance Active Cat-Back Exhaust w/ GT350 Lower Valance can be adjusted by the user with the included control module. Wiring necessary for installation is also included.
