Sorry to revive an old thread but I figured it would be better than makeing a new one.

I am having a hell of a time with both demon bolts. I have all of the other bolts out. I started by spraying with PB several weeks ahead of time. I have injen intakes so there is enough room to access the bolt from the engine bay. I have a 1/2 inch breaker bar with a couple feet of extensions and a 14mm impact socket.

At this point the bolts are partially stripped and have not budged. I've tried heating them with a torch and by running the car. I made some super PB blast I found online by mixing 1:1 ratios of ATF and Acetone. I tried an electric impact wrench wich does not slip off the bolt but did not budge it either.

The way I see it I have two options. Take it to a shop or try to break or cut the bolt off. If I cut the head of the bolt off, will I be able to remove the cat? From what I've seen, it looks like the flange it threaded so I would think it still wouldn't come off.

Anyone have any other ideas?

Thanks,
Matt
