No you guys are all wrong.... add dual exhaust it will then blow down the road.... and if you ad a forward intake that will help by sucking down the road.....also taking the glass out will reduce wind resistance.
You guys are misunderstanding the question. You need to change the grease on your rear. Lube it up real good and take it out and run it down the highway real hard. Then flush it again. Do this for an open carrier or locker.
You could drive it out the back of a C-5 Galaxy @ 30.000 ft. Acceleration will be great, so fast you'll need a parachute! Be aware, if the chute fails to slow you down, you will stop abruptly. Otherwise " You need to change the grease on your rear. Lube it up real good and take it out and run down the highway real hard."
