rx733

i just recently experienced a problem with my fd rx7. as i was driving home i heard a very faint pop. when i looked in the rear view mirror i noticed a ton of smoke blowing out. i immediately pulled over and turned off the car. i called a tow truck to take it home to avoid any more damage. when the driver pulled it on to the bed i noticed some oil coming out of the exhaust pipe. does anyone know what this could be. ive asked around and some say its the turbos blew a seal. any help is appreciated.
