Since they do look the same at most angles and in diagrams, can you use an F TYPE S muffler on a Premium and still get the F Type S sounds? Assuming you manually keep the active exhaust valves open

 

Yes. The mufflers on all F-TYPE V6/V8 are interchangeable. On the V8 you will need the valance. There isn't a perceptible sound difference between the V6 and the V6S as the snaps, crackles and pop are software controlled.
