^ Agreed completely with Spohn. I soaked one bolt with PB blaster and did nothing with the other. I then started the car for 10-20 seconds to get the bolts slightly warm. The one with the PB blaster came off nice and cleanly. The one I didn't? I sheared the stud off completely.

I used all 1/2" impact extensions, a 6 PT impact socket, and a 3' breaker bar. I also did not remove any of the intake, I only had to loosen the driver's side slightly to squeeze the socket and extensions through.

I did this all on the garage floor and it took me about 4 hours with little mechanical experience. Installing the new cats is soooo much easier, you will be using all new bolts which makes future removal much easier as well.
