I got all set to gut my precats this weekend, but found that the spring-loaded studs holding the Y-pipe to the main cat were rusted to hell...the nuts are half gone. They're not going to let the system come apart, but I'm not getting them off without cutting them either.
I went to the dealership to order new studs/nuts today...$120!!! No way. Is there:
A) A cheaper place to order them,
B) An alternative, like using regular bolts (though eliminating the springy thing concerns me about this alternative), or
C) Is it easier to remove the y-pipe/main cat as one?
I'm leaning toward trying C, but I didn't think to look at whether the bolts behind the main car are any easier. Are they? What would I need to replace them with if they must be torched off too?
THANKS....
