Omg I did one at the shop the other day. NIGHTMARE.
You can get both bolts on the housing usually.. I used a boxend non-ratcheting wrench for the bottom one... had to use a prybar to pry it up to loosen the bolt. Huuuuuge pain in the ass.
From there sometimes you can sneak it out.. best bet is to takeoff the heat shield otherwise. Just destroy it if you want, I would on my car, lol.
Good luck soldier.
