Where is the Y pipe?

I posted a question earlier about the exhaust smell. Someone told me it was the Y pipe cracked so my question is where is the Y pipe and could i replace it myself? Any pictures would help! Thanks!

The Y pipe connects to the back of the turbo. It goes from each exhaust manifold up to the turbo. There are flexible bellows towards the top of each leg of the Y near the turbo that are prone to cracking. If you have removed the turbo recently, it could be that it is not seated correctly.

y pipe is right before the z pipe

You can replace it yourself. Just move the coolant reservoir to the side, loosen the nut on the v-band clamp where the y pipe connects to the turbo and remove it. If you still have an egr cooler, you have two options. 1-disconnect the y-pipe from the up pipe closer to the turbo and the driver's side exhaust manifold bolts that connect it to the y-pipe. OR 2-disconnect the egr cooler v-band clamp at the up pipe and then remove the bolts from both exhaust manifolds where it attaches to the y-pipe (those you will have to get to from underneath the truck).
