The rule states "...shall be directed away from the car body." Best I can tell this is a binary condition: either something is pointed toward the car body or is pointed away from the car body. Notice there's no specification for direction otherwise; e.g., "up", "down", "horizontal", "vertical", "forward", "backward", etc. Just "away".

Last time I checked, pointing down toward the ground is pointing away from the car body, which in generally tends to exist above the exhaust. Given that down is away from above, I'm guessing you're good...well, I suppose unless somehow the car body is between the exhaust and the ground, which would be kinda awkward...

Personally, I liked the old Dodge L'il Red Express Truck exhausts, I think they'd look pretty awesome on an E36 BMW... - GA
