Now this is probably the best sounding flat-six powered Porsche I have ever heard! What you see here is the new 2018 Porsche 911 991 RSR GTE MK2 mid-engined testing at Monza circuit. This 991 RSR is fitted with the new center-mounted exhaust and it sounds absolutely amazing! Make sure to turn up the volume and enjoy that gorgeous 4.0 liter flat-six engine melody!
