9-inch rearend exhaust clearance issues
What are you guys with 9-inch rearends doing about exhaust? I didn't realize clearance was going to be a problem until I bolted the housing and case into the car today. The u-joint saddle is right against my Flowmaster 3" exhaust.

I had a 9" in my car for a few months and my exh would hit in the same
way with the car supported by jackstands on the sub-frames.. With the
suspension loaded, the rear sits up higher in the frame and had a good 1.5"
clearance with the exh..

this may work
I don't have quite the same set up as you, but this is what I did with my 2.5" true duals & stock rear. I ran the pipes under the axle tubes. I don't have any clearance problems. The bottom of the diff. is about the same as the bottom of the pipes. However, it will make it harder to swap out a rear if it's all welded like mine is. I can send pics. if you like.
