So my car is up on ramps and i have disconnected the mid section from the cat, and got the exhaust off the hanger in the middle but i can't get the back box off the hangers, now looking at it, it looks easiest to just cut them and get new ones to hang the exhaust on but there isn't any shops open and i need my car, anyone got any tips on how to get them off so i can re-use them...
