I hacked the catalyitc converter off with a sawzall after iI discovered that it was glowing cherry red.The bolts to the front flange of the cat are rusted solid.It looks like that I'll be able to remove what is left of the cat if I grind the heads off of the bolts that secure both sides of the flange.My question is : are both sides of the flange threaded,or just the cat flange? If I can't get this assembly apart,I'm faced with the prospect of replacing the fron exhaust pipe..
Any advice is much appreciated!!!
TIA!!!!!!!
