!! Stripped Cat Bolt !!

Taking the stock air boxes out helped a good bit, but 4 out of 5 installs you'll have to break the head off the bolt to get the stock cats out. Try to use some sort of lubricant like PB Blaster or WD-40 and let it soak for a while. Make sure the car is cooled down, otherwise the bolts will still be expanded and you'll be setting yourself up for even more fail. If you're able to get the bolt a 1/4 of a turn, use more PB Blaster and try to hit the threads if possible and work your way back and forth.

If you have to snap the head of the bolt, so be it. It's not the end of the world and you can drill and re-tap. That's what had to be done on my car.
