Instructions with what? making a downpipe? put the manifold and turbo setup on, put the plate on and start making your downpipe? Are you going to be welding your own pipe or what?

Maybe I am a bit confused on what the question is...

dood almost every downpipe is differant with each setup.

easiest is to drive to a muffler shop and have them make one.

stainless or normal pipe? flex section? 2.5/3.0 pipe? Two 02 bungs or just one?

lots of varibles when doing downpipes, so its tough to say.

I took a couple of u bends, made some cuts, marked them up, and had a buddy weld them. Simple as that. Take it to the exhaust shop if you need to.

a downpipe is never the most thrilling thing to work on, but it's pretty easy. Mine turned out decent, but came close to the front engine mount which was my only obstacle.
