Good job, shame you ended up with so many flow restrictions though.
You will need to plug chop that beast.
Are the internal joints smooth or are there places which can drum up eddy currents.
The air flow through a pipe which has sharp edges can be affected dramatically.
The inside of the pipe should be shoulder free.
My concern is that the inside of the pipe may have sharp edges on bends that will impede the air flow.
It is fine to reduce the diameter, but it must be done smoothly and gradually.
Real nice setup. Can't be any worse flow then stock .lol. How many jet sizes you have to go up will tell you how well it flows.
A sock stuffed in the intake would be better than stock, lol
Not a real good idea to use anything inside an intake, lest it comes adrift and gets sucked in.

I doubt anyone else is running a PVC Dr Seuss set up lol so any jetting advice will be guesses. I would plug chop it and see for yourself. Also I would try to straighten the design out. That set up will cause turbulence. Air and water flow very much alike. Think how water would flow through what you've created. Straighten the design and you'll be golden. Good work btw
