Check out this new video released by Youtubist Marchettino. This time he brings to us some heavy track action involving a modified Porsche 997 GT3 RS. The matte black car benefits from Manthey Racing tuning and features X-Ost exhaust system. That’s why you are advised to use headphones for this video, or crank up your speakers to max, so you fully enjoy the superb noise this thing makes.
