This year and last year we saw few Audi RS6 C8's driving around. These cars have all been fitted with an aftermarket exhaust system and OPF delete. In this video you can listen to some accelerations, revs and crackles. We saw these RS6's during the Supercarsunited Nieuwjaarsrit, Superfast Drivers Club, Zoute Grand Prix, Supercar Madness Assen and our summer holiday in Monaco.
