here ^ you said that it will flow aerodynamically... what do you bais this off of... i don't not assume that you used a wind tunnel for testing, did you?
this might be a retarded question, but im just curious, this would also apply in general, for example isn't the stock exaust supposted to be aerodynamically designed (although ugly) so if you change it, then arn't you changing the aerodynamics of the car?
sorry if this is stupid...
