Aftermarket automotive community thoughts about Fi
Why Fi was the only exhaust mod for TheStradman’s next Aventador build?

Fi EXHAUST-Signature Titanium F1 High Pitch Version was unveiled on TheStradman's 1/1 Liberty Walk Aventador Limited Edition in Rosa Acantis. Because of the unique F1 design and titanium material the sound note is reaching a higher pitch in comparison to the Volcano Version stored on the iconic purple Aventador, which is the favorite modification he’s ever done to any of his cars. 

It's an unparalleled level of craftsmanship. Increased weight saving measures went to every detail of the design to produce an ULTRALIGTWEIGHT exhaust that weighs only 8.41kg. And the Rose Gold coating sets the system apart from anything else available on the market. It’s an elegant choice and a unique system with “Strad” logo custom engraved on two center tips.

Fi 2 headers have a 4 to 1 style collector in order to increase the frequency to a higher pitch. And it sounds amazing, like a freaking F1 car.

MY GT3 FINALLY SOUNDS LIKE A GT3 SHOULD! | 992 GT3 Exhaust Install / Review

If I had to give the exhaust a DougScore if you will. I’d say sound 10 out of 10 for this car. I’d say the tone is excellent and it’s about as loud as a 992 gets. Visually I’d say 10 out of 10 as well. I love the way this exhaust looks. I’d highly recommend opting for the carbon fiber tips. And the customer service experience of getting it all taken care of has been great. I highly recommend it. - JoeKnowsBest
