now before u weld the pipe to the y piep and its in the car permantly u need to bolt it back to the turbo so u can figure out were to weld the flange for ur wastegate on.
if ur using an internal wastegate u can skip this step
mine fit perfectly right bleow the inlet flange and faces the crank pully


once u get that finished u can go ahead and bolt the pipe back to the turbo,and weld the other end onto the y pipe
ok now u have the inlet pipe done.now u have to cut the ypipe from were the rest of the ex system meets it and cap it.so all the ex gasses goto the turbo. in the picture below u can see were i cut mine and caped it.now this isnt optimal but it does work.a better way to do it would be to cut the pipe comming from the manifold short and weld a new bend in its place so when it comes down to the y pipe it makes a nice bend into it instead fo just liek dead ending into it.i would have done this myself but i was running out of tubing.and it was late sunday night so i couldnt even go get more.though i will be making a new pipe soon.when that is on the car i will edit this and post the pics.

well now u have the inlet pipe completely finished
now its time to start the downpipe.( the piep that goes back to the cat/muffler)
here u can see the flange that goes onto the turbo this is a block off flange to block off the hole for the internal wastegate.the pipe comes striaght out of the flange about 3 inches then makes a 90* turn downward

and here it is bolted to the turbo


it drops down and makes another 90* bend under the crossmember on the passengers side
which u can sorta see here (img was to large to put into the thread so click the thumbnail)

here are a few pics of it running back to the rest of the ex system.keep in mind i threw out my stock cat.if u keep urs it will look slightly diff.rout the pipe under the cm and out twards the stock ex location

and here it is gpoing out to the stock intermediate pipe.(ran out of tubing at this point so u can see were i had to weld in bits of the old stock pipe)
