Im putting an exhaust in my ls and I need to cut some of the bolts out
the three that connect the cat to the cat back they are rusted to death
and even with a breaker bar will not even break off
my question is is the rear flange on the cat threaded?
If i cut the nuts off will that funny looking flat washer like end piece still be threaded into the flange or will it just fall out like the spring bolts closer to the muffler?
sorry for the lame question and length and Thank you.
