Can I ask how do you know its all 3 pieces faulty?. I had a new exhaust fitted, but it started to hang low, because the clown who fitted it used the original 4 year old rubber hangers that were well past their best. So I went back to the garage with the whole exhaust hanging down, told him and what did he do?. Drove it up on to the ramp. Well he tried, but the back box caught the edge of the ramp, and when you put the whole inertia of the car moving onto the exhaust something's gonna give, in this case the flexible section. This is the weakest link in the exhaust, and if you have caught it, a quick repair will get you going. the original is a piece of flexible pipe welded in place, however, you used to be able to get pieces of flexible exhaust pipe, some Gun gum exhaust sealer and a couple of exhaust clamps and jobs done. This is also to be preferred because taking off the exhaust manifold, often leads to snapped exhaust studs which are a B****** to drill out and retap. Best of luck
