Taiwan-based tuner Frequency Intelligent Exhaust (Fi Exhaust) has released an ad which looks like footage taken for the Need For Speed franchise. The company is based right outside of Taipei City.
The Fi Exhaust took a Porsche 991 GT3 RS and outfitted it with a custom exhaust that features cutting-edge intelligent ECU valve control. The exhaust hardware includes a catless header and a catback Valvetronic muffler.
The catback Valvetronic muffler will allow the voice of the engine to be controlled according to engine rpm or remote control.
Towards the end of the video, you'll hear a violent high-pitched sound. This is because the valves are open.
With valves closed, the exhaust notes will be softer in order to make the drive more relaxing. Because this is a commercial, the makers gave more importance to the background music rather than the exhaust soundtrack.
