Here's What I Found
So okay this was found on the 65th anniversary of 101 Dalmatians but it's not from a 101 Dalmatians Story Board but it's from a 101 Dalmatian Street Story Board, here's the picture I found.
I know it's just a single exhaust port but it looks cool and I decided to make my own version using the 101 Dalmatians Version of the Car, now here's what I made.
Don't mind the two Cruella's but I decided to make a dual exhaust port due to the Engine being a VR8 and like the smaller VR6 Engine has two ports as vents for the toxicfuel fumes.
There was one in 101 Dalmatians 2 but it was on the right side and it was a single exhaust port which wouldn’t work for a VR8 Engine or if it did then it wouldn’t be as efficient.
