Tail Fins/Ehaust tips

Will there be tail fins in the car designer such as on American cars from the 1950’s? Also, will the player be able to select a place for and the style of the exhaust pipe? Ex: If you want double tips or single, or out of the back of the car or the side.

I cant answer for the fins, but im assuming the exhaust tips will be based on your engine design, since you choose it whilst doing so. the only exception i think would be different tips and wheather or not it is a true dual exhaust

Exhaust tip/exit styles will probably be chosable per car yes. 1950s fins will be part of the base body of some of the 1950s designs

side draft exhausts? <3

Mercedes SLR? Exhaust tips in front of the doors?
