Intake project... need help on ideas/input.

Im trying to clean up my engine bay. I already hid some wires on the passenger side (starter solenoid ETC). I also plan on putting the battery in the trunk. Im now focussing on the passenger side. the Carbon Canister line has already been hid. I also plan on tucking the MAF wires, relays ETC away in the Pass fender. But, I HATE the look of the stock intake tubing. i dont like the MAF mount also. I like the idea of a N/A powerpipe, but I can't justify 200+ bucks for a peice of tubing, plus they only work with Pro M MAFs, something else I dont have.

I had decided to make an adapter for the 95GT Maf I plan on using anyway, so instead Im just gunna make my own Powerpipe type intake to fit my needs. Heres where I need a little help. Would 3 inch exhaust pipe be ok? Im running a 70mm TB, which is smaller than 3 inches, would this cause a problem? My air filter is HUGE like 9 inches or something, would I have to get a smaller one? What direction (generally speaking) should I make the pipe (inside the fender) to direct the MAF, downwards slightly? Where can i get BLACK tubing to connect the piping the the TB and MAF? I hate that blue stuff that comes with BBK intake kits and S/C kits.

Just for reference, here are some measurements I took:
TB- 70mm (2.75 inches)
Fender opening (Approx)- 3.5 inches
Intake side of the MAF opening- 3 Inches
Filter Side of the MAF opening- 3 3/8 inches
Thanks alot guys, any input or criticisms are welcome.

Thanks alot... i just want to make sure i dont use the wrong size piping and that there wont be problems with tthe MAF in the fenderwell.
