LOTS of PB Blaster or Kroil for several days is a start. Do a search for removing exhaust nuts and there are some great tips to be found.


Be prepared to buy new studs/nuts as it sounds like the currents ones may not be reusable.

This is a good thread on what/how to remove the exhaust.

not tried it on 911 bolts but i have used O/A to heat them and get them off.
