going to be installing a downpipe tonight
 

is it difficult? I we do it with just normal hand tools?

Anything i should be on the lookout for?

Best question ever: is there a write-up on it anywhere?

No, it is fairly simple to swap out. You will need a mid 14 3 in. extention, a ratchet, and a breaker bar for the top of the down pipe.Keep your hands away from the shields on the turbos and the one one the brakes. You will also have to take out the intakes. the bolts on the back of the pipe should be 17's but you never know until you look.
