Turbo-back & Downpipe clarification

I need clarification.

1. Do the turbo-back exhaust systems include the downpipe piece coming straight off the turbo? (You'd be surprised how dense I am):dunno:

2. Does a 4" MBRP turbo-back straight pipe installer series have a true 4" downpipe or a 3.5"?

3. Do the 5" MBRP turbo-back straight pipes have a 4" downpipe?

Thanks for shedding light!

Yes turbo back comes with new down pipe. And my mbrp 4 inch kit had a 4 inch down pipe.
