Installing Accurate dual exhaust on ‘67 Barracuda

My local shop just built a 2.25" dual pipe on my 67 fastback. It is a little ugly with butt welds, but it comes out right at the valance. I also have the 68 valance with dual rectangular cutouts, and 68 tips. They didn't do anything to the tank or the hanger, except slip a short piece of hose over the j-bolt so the threads don't rub against the pipe. Not a lot of clearance anywhere around the rear spring and axle.
