I made a custum full intake for my 88 GXL. My only problem is I used an arrogated tubing, so I get a spiral affect the whole way, doesnt sound the prettiest and I've been told for ever spiral it's acutally like 2-5 feet straight pipe. what is good though is it's about 4 inches wide, so I get a lot of air.

So my quiestion is, where, and what can I use that is cost efficient, but a straight smooth pipe and still gives me the flexibility of my sprial air duct look alike thing.
