Fi finds the perfect balance between valves shut and open modes.
Fi EXHAUST Super Sport version is an excellent option for a daily driver, because it provides the best of both worlds. It’s the most tame sounding Fi GT-R exhaust version with valves closed making it a perfect sleeper when valves do eventually open. Paul Wallace was surprised about how different Street and Race sound profiles sounded: “It’s a stainless steel back box, de-cats running all the way through the car. So you expect it to be loud, but you never expect things to be quieten down so much. I’ve had decat cars in the past on valve control. They just don’t get tonal differences between ON and OFF. Frequency Intelligent accentuates that noise that just ripples through your body. It will use anything to bounce that sound back to you.”
