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.
^This guy mentions using new bolts. I bought my HFCs used and the guy didn't give me any bolts. Is it necessary to use new ones and, if so, where can I buy them from?

Same situation I had, if you know the sizes you can just goto home depot and buy them. I was told by the company that made my hfcs some mixed (and wrong) info...basically theres one stud attached to the header side, so you'll at least need two new bolts n nuts per side.

OEM hardware could work but thats provided nothing breaks during removal
