the exhaust leak was fixed prior to the fire... and its ceramic coated and heat wrapped, so i doubt without the leak it was getting hot enough to burn through any kind of line

update is that repairing it may take more time/money than I really want to spend. My plan is to get into racing, and the subaru would never be competitive in any kind of class... I am considering parting it out and running a historic 911 as a track/race car with different setups for each (seeing as the race engine has to be rebuilt every 30-40 hours)

If I do decide to go this route, I will post the partout up... or if anyone wants to buy the whole car and just swap a new engine bay in. The cage is worth quite a bit of money
