Mustang down
 

I went to start my 2004 Mustang GT, I heard a mettallic bang , so shut it down . I fired it up again and it started ,but made a sound like an big exhaust leak.( passenger side ) I shut it down and had it towed home .I am a disabled pensioner so I dont have big money to fix it, any ideas of where I can start to look for the problem . Thanks in advance .

Does it have oil pressure when it's running? Do you think it's exhaust or internal engine issue? If it's exhaust it should be fairly easy to spot.
