I take it when you say the exhaust “was scraping the floor” you mean it was touching the ground not the floor of the car.
This is the problem with the Mk2 Fiesta exhausts, the entire rear of the system is offset across the car and only has supports on the outside of the system. It relies on the clamp between the exhaust and the downpipe to stop the exhaust system twisting as you’ve found. It maybe that you’ve got a slight mismatch in size between the new downpipe and the old exhaust system and the joint can’t be tightened enough to stop the rotation. If there is a gap you maybe able to shim it using a strip of metal cut off a old tin can or similar. Use silicone sealant on the joint as well, works much better than the old exhaust paste. This is why i think the downpipes crack as well, they are taking all the twisting force from the weight of the exhaust system trying to turn. I’ve added some extra support brackets on the exhaust on my Mk2 and Quantum 2+2 and saloon so that the exhaust system is self supporting without being connected to the downpipe.
