Yes it is all very necessary... its tough enough to get them in without the stuff on let alone with it on. I just unbolted the trans and motor mount and jacked up the engine a bit from the oil pan. I also took off all the spark plugs, just to avoid any damage... i would recommend this. All in all it took about 6-8 hours and i'd like to say we knew what we were doin. btw, its a very messy job. What mid pipe are you goin with?
