Try fastening the exhaust to the body with cable ties, it will take the slack out of the exhaust rubbers. It will pull it up abit, worked for me long enough to get engineered lol. Car was over 100mm, but exhaust hung around 70/80mm from the ground and I managed to bring it up. Give it a go, it doesn't last long (cable ties). But a good idea for all with low cars, maybe use metal clips for longer lasting use.
