I recently bought a 2003 H2 with 49k miles it has winch offroad roof lights, the stock 4 round configuration, and two more roof bars after, and air suspension

Anyways, the roof is very dirty and the bars were kind of creating a place for the dirt and crap to build up, so I decided to take them off

I figure since they probably decrease my aerodynamics by taking them off my mpg would go up

And as I figured my mpg went up with city driving I'm getting 12.2mpg in stop and go, haven't tried the interstate yet..
Before with them I know I was getting about 13.5 mpg going 60mph on the interstate.

Anyway, since I've taken them off (roof bars and offroad roof lights) the wind noise has increased and I don't see why that would happen any ideas?
