I will be putting 3" duals on and was wondering if anyone has run the pipes under the rear axle instead of over.

If so how much clearance did you give the axle and does the axle ever drop enough to hit it.

someone said they did but I don't think its a good idea on a non-independent rear suspension car.

hummm. would that not be impossible, because when you jack up the rear of your car the rear end goes down becasue theres no weight on it. for it to clear that problem you would have the exhaust like 1 foot under the rear and when you drop it back down you would be sitting on your mid pipe. i dont think that is possible.
