What is the best way to remove the rear bolts on catalytic converter? I have a new ZZ performance down pipe for a 2001 GTP.
 


Soak them in PB blaster for a while... the put your ratchet on it and pull like a mofo. May have to use cheater bar.... or torch them if they break off.
 
Blaster and similar lubricants are flamable, don't use a torch!


Let some blaster soak on the bolts, then get a wrench on one side, impact on the other.

If that doesn't work, drill the bolts out and replace with new ones.
