The car is amazing, the presenter on the other hand is the typical annoying youtuber talking nonsense constantly. I wanted to hear the F1 car soundtrack in a saloon body but I gave up after a couple of minutes of this idiots jabbering!
I believe its an equal length header exhaust which gives it that 90s Formula 1 kind of sound, theres a Silver S600 with a similar exhaust which was done in Japan but is now in the UK, seen it on instagram
Someone seems to have put his videos from instagram on Youtube
Also I'm reminded of this old Countach video which has had a similar exhaust treatment I think
