etk 800 missing tailpipes

Title says enough. Mufflers look like they dead end. Same problem on both exhausts (I4 and I6).

 

That's because the exhaust tail piece is part of the rear diffuser.

 

and that is unrealistic. there should be at least a hole or two in the exhaust, depending on the engine...but i think they should be apart from the diffuser...

 

I know it'sounds unrealistic. But why the game developers made it that way, I don't know why. Must something though.

 

but is there a staff member that could answer to this? hope so
