very easy, and fun too. use some ramps, i use ramps rather then jack stands. just make sure what ever you use to get your car in the air, have some sort of back up. like blocks or wood... just incase the stands or ramps fail. dont get under your car with just a jack, thats a no no. i have found that soaking the bults with ALOT of wd40while they are just a bit warm works the best. have a friend help you when you take off the stocker, its pretty heavy.

Soak everything you're going to unbolt in WD40 or PB Blaster. It makes things 100x easier. I wouldn't have been able to do my catback without PB.

its not hard like everyone said, just set aside a good amount of time just in case you runinto problems. make sure you get a few long extensions, a swivel, and a long pipe to use for leverage. the header bolts are tight as a ****.
