Do you know of anything to prevent the melt down and what sort of damage is caused?[/QUOTE
the exhaust hangers bolt to the car at the rear under the diffuser,put washers between them and the car to prevent this,it drops the exhaust down by however many washers you put in but i'd say about 10mm is about right,i used 3 penny washers per bolt
a tip i learnt from a certain Mr Foxspeed
