Can someone who has done it give me some dimentions on how to make a pvc pipe intake for my tpi 305 ... Or at least a good pipe diameter .... i know alot of people hav done it because of the shortage of intake kits for 3rd gen....oh and a estimated cost would be cool too thanks alot.

 

Look in the 'Fabrication' board... its a pretty popular topic there

 

3", dont use anything thin like PVC or Vinyl tubing, it wont hold up under the heat. Use ABS like sewer pipe and connections, it wont warp or melt.
